Tadaruk privacy

Last updated 30 October 2026

Tadaruk is operated by SOFTIUM Sàrl (Softium LLC), Rue des Musées 58, 2300 La Chaux-de-Fonds, Switzerland (UID CHE-303.047.962), which is responsible for your data. This policy covers Tadaruk only. We follow the Swiss Federal Act on Data Protection (FADP) and, for users in the EU/EEA, the GDPR. Use of Tadaruk is subject to Softium's Terms. Questions or requests: contact us through softium.ch.

What we store

• Your name and email address from the account you sign in with.
• A coarse location (rounded to about 1 km) and your timezone, to calculate prayer times.
• Your settings, prayer statuses, and qada prayer and fasting counts.
• Push notification subscriptions for the devices where you turn notifications on.
• For Google Calendar: access tokens that let us manage the one calendar Tadaruk creates.

We don't sell your data, show ads, or use analytics or tracking cookies. The only cookies are the ones that keep you signed in. Prayer times are calculated by Tadaruk itself; no prayer-time service sees your location.

Signing in

Each sign-in provider shares only your basic profile with us. We never see your password.

• Google shares your name, email address and profile picture. Google Privacy Policy.
• Apple shares your name (only the first time) and an email address, which may be an Apple private relay address if you choose “Hide My Email”. Apple Privacy Policy.
• Microsoft (Outlook.com, Hotmail, work or school accounts) shares your name and email address. Microsoft Privacy Statement.
• Email: we send a one-time sign-in link to the address you enter, through our email provider Resend.

Google Calendar

If you connect Google Calendar, Tadaruk asks only for the calendar.app.created permission. It lets Tadaruk create one calendar (“Prayers · Tadaruk”) and manage the events in it. Tadaruk cannot see, read or change any of your other calendars or events. We use this access only to keep your prayer events and their colors up to date.

Tadaruk's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We don't use Google data for advertising, don't sell it, don't use it to train AI models, and don't let people read it except where you ask us for help, for security, or where the law requires it.

Calendar links (Apple, Outlook and others)

Apple Calendar, Outlook and other apps get your prayer times from a private link unique to you. Anyone who has the link can see your prayer schedule and statuses, so keep it private. You can make a new link at any time, which stops the old one working. Your calendar app (Apple, Microsoft or another provider) fetches and stores these events under its own privacy policy.

Services we use

• Vercel: hosts the app (servers in Frankfurt, Germany). Privacy
• Neon: stores the database (Frankfurt, Germany). Privacy
• Cloudflare: runs a timer that tells the app when to check prayer times. It handles no personal data. Privacy
• Resend: sends sign-in emails. Privacy
• Location lookups, only when you set your location: searches go to Google Maps or OpenStreetMap (Nominatim); a “near me” lookup sends rounded coordinates to BigDataCloud; the timezone comes from Open-Meteo. IP-based location uses our hosting provider's own data.
• Push notifications are delivered through your browser's push service (Apple, Google or Mozilla), which sees the notification text.

Some of these providers may process data outside Switzerland and the EU, for example in the United States. Where that happens, it is covered by the safeguards the law requires, such as standard contractual clauses or the Swiss–US and EU–US Data Privacy Frameworks.

Your choices

• You can see and change everything about your account in the app.
• Export your data anytime from Settings → Your data: everything as JSON, or your prayer log as CSV.
• Delete your account in Settings. This permanently removes your data from our database. Disconnecting Google Calendar also lets you delete the Tadaruk calendar from Google.
• Revoke Tadaruk's access at any time: Google, Microsoft, or Apple (Settings → your name → Sign in with Apple).
• You can ask us for a copy of your data, a correction, or deletion, and you can complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC) or your local data protection authority.
