PRIVACY NOTICE

Last updated May 26, 2026

Thank you for choosing to be part of our community at OneCal. We are committed to protecting your personal information and your right to privacy. If you have any questions or concerns about our policy, or our practices with regards to your personal information, please contact us at contact@onecal.io.

When you visit our Site or use our Service, you trust us with your personal information. We take your privacy very seriously. In this privacy notice, we describe our privacy policy. We seek to explain to you in the clearest way possible what information we collect, how we use it and what rights you have in relation to it. We hope you take some time to read through it carefully, as it is important. If there are any terms in this privacy policy that you do not agree with, please discontinue use of our Site and the Service.

Unless stated otherwise, this Privacy Policy applies to Personal Data for which OneCal acts as a controller, such as when you visit our Site, create an account for our Services, or use our mobile apps (iPhone and Android).

WHO IS THE DATA CONTROLLER?

In Short: OneCal SHPK is the controller of personal data we process about you for our own purposes (such as your account, billing, and product analytics). For personal data you upload or collect through OneCal (such as your invitees' booking details), you are the controller and OneCal acts as your processor.

OneCal SHPK ("OneCal", "we", "us", "our") is a company established in Albania, with its registered office at Rruga Gjon Buzuku, Apartamenti nr.2, Kati 7, Tirana, Albania. OneCal SHPK acts as the data controller for personal data we process about you in connection with our Site and the Service (for example, your account data, billing data, support communications, and product analytics). Our processing of that data is described throughout this policy.

When OneCal acts as your processor

For personal data of third parties that you upload to OneCal or that is collected through your use of the Service (for example, your invitees' names, email addresses, and booking responses), you act as the controller under the GDPR and OneCal acts as your processor. Our standard Data Processing Addendum, including the European Commission's Standard Contractual Clauses for international transfers, is available on our DPA page. Invitees who want to exercise data protection rights over data collected via a booking page should contact the booking page owner in the first instance; OneCal will support reasonable requests forwarded to us by the controller.

Team Accounts

If your access to OneCal is provided through a Team Account purchased by an organisation, the organisation (acting through its Admin) is the controller of your Account configuration and any data you process through the Service in connection with your work for that organisation. OneCal acts as the processor for that organisation. The Admin may have visibility into, and control over, your Account within the Team Account.

For any matter relating to this privacy policy or to exercise the rights described below, you can contact us at contact@onecal.io.

WHAT WE WILL NOT DO WITH YOUR DATA

In Short: We do not sell your personal data, we do not analyse the content of your data in bulk, and we do not use it to train AI or machine-learning models.

No sale of personal data. OneCal is funded entirely by paid subscriptions. We do not sell, rent, or trade your personal data, your calendar data, or the personal data of your invitees to third parties for any purpose, including advertising. Sharing with sub-processors who act on our behalf to deliver the Service is described in 'WILL YOUR INFORMATION BE SHARED WITH ANYONE?' below.

No bulk content analysis. We do not run bulk content analysis on the content you process through the Service (such as the contents of your calendar events, your booking responses, or your booking pages) for advertising, profiling, lead generation, or any other purpose unrelated to operating the features you use. Automated systems read your data only on a per-operation basis as needed to deliver the Service (for example, to mirror an event between connected calendars during a synchronisation run).

No AI training on your content. We do not use the content of your data, including the content of events on your connected calendars, your bookings, or your booking-page text, to train artificial intelligence or machine-learning models, and we will not do so without your express prior permission.

Staff access is the exception, not the rule. Our personnel access individual records only when strictly necessary to investigate a specific support request, respond to a security incident, or comply with a legal obligation, subject to the safeguards described under 'HOW DO WE KEEP YOUR INFORMATION SAFE?' below.

WHAT INFORMATION DO WE COLLECT?

Personal information you disclose to us

In Short: We collect personal information that you provide to us such as your name and contact information.

We collect personal information that you voluntarily provide to us when registering at the Site or for the Service, expressing an interest in obtaining information about us or our Service, or otherwise contacting us.

The personal information that we collect depends on the context of your interactions with us, the Site, and the Service, the choices you make and the features you use. The personal information we collect may include the following:

Name and Contact Data. We collect your first and last name and email address.

Authentication Data. We use passwordless authentication via magic links sent to your email address. We do not collect or store passwords. We also support sign-in through your Google or Microsoft account (see “How do we handle your social logins?” below).

Payment Data. We do not collect or store payment information such as credit card numbers or security codes. Payments are processed entirely by our third-party payment processor (acting as Merchant of Record), and any payment data you provide is collected and handled directly by them under their own privacy policy. We receive only the billing metadata necessary for accounting and tax purposes, such as transaction confirmations, plan details, and country of residence.

Third-Party Sign-In Data. We provide you with the option to register or sign in using your Google, Microsoft, Apple, or enterprise SSO account. If you choose to register in this way, we will collect the information described in the section called “HOW DO WE HANDLE YOUR SOCIAL LOGINS” below.

User-Generated Content. When you publish content through the Service (for example, your booking pages, public calendar feeds, or any similar feature we make available), you may upload a name, description (including custom links), cover image, profile picture, or other media. We store and display these items as needed to operate the content you publish. We apply a noindex directive to publicly accessible surfaces such as booking pages and public calendar feeds so they are not indexed by search engines, but depending on the visibility settings you select, this content may still be visible to anyone with the URL.

Abuse Reports. If you report a booking page or other content for abuse, we process the information you submit (the URL or content reported, the category and description of the alleged abuse, and any contact details you choose to share) so that we can investigate and take action. Our legal basis is our legitimate interest in maintaining a safe and trustworthy Service (Art. 6(1)(f)).

Calendar Connection Data. When you connect a calendar account (such as Google, Microsoft, or Apple), we store the credentials required to access it on your behalf. For Google and Microsoft, this is the OAuth access and refresh tokens issued by the provider; for Apple, it is an application-specific password that we additionally encrypt at the application layer before storing. We also store the email address of the connected account, the scopes you granted, and the connection status. We use these credentials only to perform the synchronisation and scheduling operations you ask the Service to perform, and you can revoke them at any time by disconnecting the calendar from OneCal or by revoking access from the provider's own security settings.

Calendar Metadata. For each calendar you connect, we store metadata about the calendar itself, such as its name, the provider's calendar ID, time zone, colour, and whether it is shared or read-only. This metadata is used to display your calendars in the Service and to apply your synchronisation and booking configuration.

Event content. We do not persistently store the content of events that live on your connected calendars (such as event titles, descriptions, locations, or attendees). When you configure a synchronisation, we read events from the source provider's API and write the fields you have chosen to mirror to the target provider on a per-operation basis, without retaining a long-lived copy of that event content on our systems. The exception is bookings that are created through OneCal's own booking links and similar features: those bookings are our product data and are stored in our database (booking time, attendee names and email addresses, custom-field responses, and similar) for as long as the booking exists.

All personal information that you provide to us must be true, complete and accurate, and you must notify us of any changes to such personal information.

Information automatically collected

In Short: When you visit our Site or use our Service, limited technical data (such as IP address and user-agent) is automatically logged by our hosting provider for security and operational purposes. Analytics and other non-essential cookies are only loaded if you accept them in our consent banner.

Our hosting provider records standard server access logs (including IP address, browser and device type, operating system, language preferences, and referring URLs) to keep the Site and the Service secure, prevent abuse, and diagnose technical issues. These logs are retained only for as long as necessary for those purposes. If you accept the “measurement” category in our consent banner, we additionally load privacy-focused analytics tools that help us understand how the Site and the Service are used. You can change your choice at any time via the “Cookie preferences” link in the footer.

We use cookies and similar technologies, grouped into “necessary” (always on) and “measurement” (consent-required) categories. You can review and change your preferences at any time in the consent dialog.

WHAT ARE OUR PURPOSES AND LEGAL BASES FOR PROCESSING?

In Short: We process your personal data for specific purposes, each justified by a legal basis under Article 6 of the GDPR.

Under the GDPR, we must inform you of the purposes for which we process your personal data and the legal basis for each purpose. We rely on the following bases:

• Service delivery: account creation, authentication, calendar synchronisation, booking pages, public API and outbound webhooks. Legal basis: performance of a contract (Art. 6(1)(b)).
• Billing, subscription management, and tax and accounting record-keeping. Legal basis: performance of a contract (Art. 6(1)(b)) and legal obligation (Art. 6(1)(c)).
• Transactional and security email such as magic links, booking confirmations, and account or security notifications. Legal basis: performance of a contract (Art. 6(1)(b)) and our legitimate interest in keeping accounts secure (Art. 6(1)(f)).
• Customer support handling via chat and the contact form. Legal basis: performance of a contract (Art. 6(1)(b)) for customers, and our legitimate interest in responding to inquiries (Art. 6(1)(f)) for prospects.
• Security, fraud and abuse prevention: login attempt records, rate limiting, banned-user list, and one-way hashed identifiers retained after account deletion. Legal basis: our legitimate interest in protecting the service and its users (Art. 6(1)(f)).
• Product analytics and session diagnostics. Legal basis: our legitimate interest in understanding product usage (Art. 6(1)(f)), subject to your consent for non-essential cookies under ePrivacy rules.
• Marketing and lifecycle email. Legal basis: your consent (Art. 6(1)(a)) where required, or our legitimate interest in soft opt-in to existing customers (Art. 6(1)(f)).

WILL YOUR INFORMATION BE SHARED WITH ANYONE?

In Short: We only share information with your consent, to comply with laws, to provide you with services, to protect your rights, or to fulfill business obligations.

More specifically, we may need to process your data or share your personal information in the following situations:

• Business Transfers. We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
• Vendors, Consultants and Other Third-Party Service Providers. We may share your data with third party vendors, service providers, contractors or agents who perform services for us or on our behalf and require access to such information to do that work. Examples include: payment processing, data analysis, email delivery, hosting services, customer service and marketing efforts. We may allow selected third parties to use tracking technology on the Site or through the Service, which will enable them to collect data about how you interact with the Site and the Service over time. This information may be used to, among other things, analyze and track data, determine the popularity of certain content and better understand online activity. We do not sell, rent, or trade your personal data to third parties; see 'WHAT WE WILL NOT DO WITH YOUR DATA' above.
• Affiliates. We may share your information with our affiliates, in which case we will require those affiliates to honor this privacy policy. Affiliates include our parent company and any subsidiaries, joint venture partners or other companies that we control or that are under common control with us.
• Business Partners. We may share your information with our business partners to offer you certain products, services or promotions.

For the current list of sub-processors that handle personal data on our behalf (including infrastructure, payments, email delivery, analytics, and customer support providers), see our Sub-processors page.

DO WE USE COOKIES AND OTHER TRACKING TECHNOLOGIES?

In Short: We use cookies and similar technologies, grouped into clear categories. Non-essential categories are only set with your consent, which you can change at any time.

Our Site and the Service use a small set of strictly-necessary technologies to function (for example, remembering your consent choice). With your consent, we also use measurement / analytics tools to understand how the Site and the Service are used. On your first visit, a consent banner asks you to accept or reject this non-essential category. You can change your choice at any time using the cookie-preferences link below. Your browser settings also let you block or delete cookies directly; doing so may affect how parts of the Site or the Service function.

Manage cookie preferences

HOW DO WE HANDLE YOUR SOCIAL LOGINS?

In Short: If you choose to register or log in to the Service using a social media account, we may have access to certain information about you.

Our Service offers you the ability to register and log in using your Google, Microsoft, Apple, or enterprise SSO account. Where you choose to do this, we will receive certain profile information from your identity provider. The profile information we receive typically includes your name, email address, and profile picture.

We will use the information we receive only for the purposes that are described in this privacy policy or that are otherwise made clear to you in the Service. Please note that we do not control, and are not responsible for, other uses of your personal information by your identity provider. We recommend that you review their privacy policy to understand how they collect, use and share your personal information, and how you can set your privacy preferences on their sites and apps.

IS YOUR INFORMATION TRANSFERRED INTERNATIONALLY?

In Short: We may transfer, store, and process your information in countries other than your own.

Our servers are located in the US. If you are accessing our Site or using our Service from outside the United States, please be aware that your information may be transferred to, stored, and processed by us in our facilities and by those third parties with whom we may share your personal information (see “WILL YOUR INFORMATION BE SHARED WITH ANYONE?” above), in the United States and other countries.

If you are a resident in the European Economic Area, your personal data may be transferred outside the EEA to OneCal and to our sub-processors, wherever they maintain operations. We rely on the European Commission's Standard Contractual Clauses (SCCs) as the safeguard required under Article 46 of the GDPR. A copy of the safeguards in place for any specific transfer is available on request at contact@onecal.io. View the Sub-processors page.

WHAT IS OUR STANCE ON THIRD-PARTY WEBSITES?

In Short: We are not responsible for the privacy or security of any third-party websites or services that may be linked to from our Site or the Service.

Our Site and the Service may contain links to third-party websites, online services, or applications that are not operated by us, for example links to integration partners, sub-processor documentation, our social media profiles, or external references in our blog. We do not run advertising on the Site or in the Service. We do not control these third parties and are not responsible for their content, privacy practices, or security. Any data you share with them is governed by their own privacy policies, which we recommend you review.

HOW LONG DO WE KEEP YOUR INFORMATION?

In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this privacy policy unless otherwise required by law.

We retain personal data for the periods set out below, drawn from our internal Records of Processing Activities. Where a longer period is required or permitted by law (such as tax or accounting obligations), we retain the data for that period instead.

Specific retention periods by category:

• Account and profile data: retained until you delete your account.
• Authenticated sessions: expire after 30 days.
• Login attempt records (email, IP address, outcome): retained indefinitely for abuse and fraud prevention.
• One-way hashed identifiers of deleted accounts and blacklisted calendar accounts: retained indefinitely to prevent banned users from re-registering.
• Application logs: 1 week.
• Outbound email records, delivery and bounce events, and the suppression list: retained indefinitely, to honour unsubscribe and bounce signals and to provide a delivery audit trail.
• Booking records: retained until you delete them or close your account. Booking events that have already been written to a connected calendar provider may persist on that provider's side independently.
• Product analytics events (PostHog): 90 days.
• Marketing-platform contact records (Brevo): deleted when you delete your OneCal account.
• Tax and invoicing records of record are held by our merchants of record (Paddle for web, and RevenueCat with Apple / Google Play for mobile in-app) per their statutory retention periods.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize it, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.

HOW DO WE KEEP YOUR INFORMATION SAFE?

In Short: We follow industry security best practices to protect your personal information, including encryption in transit and at rest, isolated production databases, strict access controls, regular backups, and periodic reviews of our sub-processors.

We have implemented appropriate technical and organisational measures designed to protect the personal information we process against unauthorised access, disclosure, alteration, and loss. Our security practices include:

• Encryption in transit (TLS) for all traffic between you and our Site or the Service, and encryption at rest for production databases and backups.
• Production databases isolated from the public internet, accessible only through authenticated, restricted network paths.
• Role-based access controls and least-privilege principles for personnel accessing production systems, protected by strong authentication.
• Automated, encrypted database backups to support disaster recovery.
• Periodic security reviews of our sub-processors and contractual safeguards covering the personal data we entrust to them.
• Standard physical and operational security measures for staff devices and workspaces.

In the unlikely event of a personal data breach, we will comply with our notification obligations under Articles 33 and 34 of the GDPR, informing the competent supervisory authority and, where required, affected users without undue delay.

However, please remember that no method of transmission over the internet or method of electronic storage is 100% secure. While we use commercially reasonable means to protect your personal information, we cannot guarantee absolute security. You should keep your account credentials confidential and access the Service only within a secure environment.

DO WE COLLECT INFORMATION FROM MINORS?

In Short: We do not knowingly collect data from or market to children. We require all users to be at least 18 years old, or at least 16 years old if they reside in the European Economic Area.

We do not knowingly solicit data from or market to children. By using the Site or the Service, you represent that you are at least 18 years old (or at least 16 years old, if you reside in the European Economic Area), or that you are the parent or guardian of such a minor and consent to that minor’s use of the Site or the Service. If we learn that personal information from a user below the applicable minimum age has been collected, we will deactivate the account and take reasonable measures to promptly delete such data from our records. If you become aware of any data we may have collected from a child below the applicable minimum age, please contact us at contact@onecal.io.

WHAT ARE YOUR PRIVACY RIGHTS?

In Short: In some regions, such as the European Economic Area, you have rights that allow you greater access to and control over your personal information. You may review, change, or terminate your account at any time.

In some regions (like the European Economic Area), you have certain rights under applicable data protection laws. These may include the right (i) to request access and obtain a copy of your personal information, (ii) to request rectification or erasure; (iii) to restrict the processing of your personal information; and (iv) if applicable, to data portability. In certain circumstances, you may also have the right to object to the processing of your personal information. To make such a request, please use the contact details provided below. We will consider and act upon any request in accordance with applicable data protection laws.

If we are relying on your consent to process your personal information, you have the right to withdraw your consent at any time. Please note however that this will not affect the lawfulness of the processing before its withdrawal.

Right to lodge a complaint

If you are in the European Economic Area, you have the right to lodge a complaint with your local data protection supervisory authority if you believe our processing of your personal data infringes the GDPR. You can find the list of EEA supervisory authorities on the European Data Protection Board's website at https://edpb.europa.eu/about-edpb/about-edpb/members_en. You can also contact us directly at contact@onecal.io to try to resolve the matter first.

Automated decision-making

We do not engage in automated decision-making, including profiling, that produces legal effects concerning you or similarly significantly affects you within the meaning of Article 22 of the GDPR.

Account Information

You can review and update your account information at any time from your account settings.

You can permanently delete your account at any time directly from your account settings. When you do, we delete your personal data from our active production systems, including your profile information, calendar synchronisation tokens, booking pages, and any data we hold from the third-party calendar providers you connected. A small set of records is retained beyond deletion as described in the “How long do we keep your information?” section above. Specifically: one-way hashed identifiers used to prevent abuse and re-registration with banned accounts, limited security and audit logs, outbound transactional email metadata, and financial records held by our Merchant of Record under their statutory retention obligations.

Opting out of email marketing: You can unsubscribe from our marketing email list at any time by clicking the unsubscribe link in any marketing email we send, or by contacting us at contact@onecal.io. You will then be removed from the marketing email list. However, we will still need to send you service-related emails that are necessary for the administration and use of your account.

DO CALIFORNIA RESIDENTS HAVE SPECIFIC PRIVACY RIGHTS?

In Short: Yes, if you are a resident of California, you are granted specific rights regarding access to your personal information.

California Civil Code Section 1798.83, also known as the “Shine The Light” law, permits our users who are California residents to request and obtain from us, once a year and free of charge, information about categories of personal information (if any) we disclosed to third parties for direct marketing purposes and the names and addresses of all third parties with which we shared personal information in the immediately preceding calendar year. If you are a California resident and would like to make such a request, please submit your request in writing to us using the contact information provided below.

If you are under 18 years of age, reside in California, and have a registered account with the Service, you have the right to request removal of unwanted data that you publicly post through the Service. To request removal of such data, please contact us using the contact information provided below, and include the email address associated with your account and a statement that you reside in California. We will make sure the data is not publicly displayed through the Service, but please be aware that the data may not be completely or comprehensively removed from all our systems.

OneCal's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the “Limited Use” requirements.

If you have any questions or wish to contact us about this Disclosure, please contact contact@onecal.io with the subject of “Google API Disclosure”.

DO WE MAKE UPDATES TO THIS POLICY?

In Short: Yes, we will update this policy as necessary to stay compliant with relevant laws.

We may update this privacy policy from time to time. The updated version will be indicated by an updated “Revised” date and the updated version will be effective as soon as it is accessible. If we make material changes to this privacy policy, we may notify you either by prominently posting a notice of such changes or by directly sending you a notification. We encourage you to review this privacy policy frequently to be informed of how we are protecting your information.
