Privacy

PrayCalc is built to require minimal data. Prayer times are a mathematical calculation — we do not need an account to show you accurate times, and most of the app works without one.

What we collect

Location data

Prayer times require a location. We handle this two ways:

• GPS (on-device): Your device's GPS provides a coordinate. The coordinate is sent to our API to calculate prayer times and is not stored.
• City search: You type a city name. We return matching results. The city you pick is stored locally on your device (not on our servers) for quick access next time.

We do not build a location history. We do not track your location in the background.

Account data (optional)

Creating an account is optional. If you create one, we store:

• Email address
• Display name (if you set one)
• Your saved locations and settings (so they sync across devices)
• Prayer tracking data (if you log prayers)

You can use PrayCalc without an account — the web app and mobile apps work fully without signing in.

Usage analytics

We use Umami, a privacy-focused, self-hosted analytics tool. Umami collects:

• Page views and navigation paths
• Browser type and OS (aggregated)
• Country (from IP, not stored)
• Referring source

Umami does not use cookies, does not track individuals across sessions, and does not sell data. No third-party analytics scripts are loaded.

Crash and error reporting

We use Sentry to capture crash reports and error logs. Sentry reports include stack traces and device info (OS version, app version). They do not include personal data or location.

In-app purchases

Subscription and purchase management is handled entirely by Apple (StoreKit 2) or Google (Play Billing). We receive a transaction receipt confirming entitlement but do not receive or store your payment card details.

What we do not collect

• No advertising identifiers (IDFA, GAID)
• No browsing history
• No contact lists or social graph
• No biometric data
• No background location

Data sharing

We do not sell your data. We do not share personal data with advertisers. The only third parties who receive data are:

• Sentry: crash reports (no PII)
• Apple / Google: purchase transactions (handled by their systems)
• Vercel: web hosting (processes request metadata per their privacy policy)

Data retention

Account data is kept as long as your account exists. When you delete your account, all personal data is permanently erased within 30 days. See Account-Deletion for instructions.
