How we protect your privacy

Privacy Policy

Last updated: May 11, 2026

Mahayom is designed for quiet daily use that respects your privacy. This document describes, in plain language, what data we see, what we do with it, and - more importantly - what we never touch.

What stays on your device

• Your settings: language, nusach, calculation method, your location (GPS coordinates or a city you picked manually), notification preferences.
• Scheduled reminder history, computed locally from your settings.
• Home screen widget data, prepared on-device for display.

All of this lives in local storage on your device. None of it is sent to any server, and we have no way to see it.

Your location

If you grant GPS permission, your precise coordinates are stored only on your device and used solely to compute halachic times. They are never transmitted anywhere. If you prefer, you can pick a city manually in Settings instead of GPS, and the device's location service is never queried.

Important to mention: any network request (like with any app or website) exposes your IP address, from which Google's servers can infer the country you're in - not the city, and certainly not the address. This is general statistical information, not data that identifies you.

What goes over the network

1. Basic usage measurement. So we know how many people actually use the app and can prioritize fixes, we measure basic actions through Firebase Analytics (a Google service): how many times the app is opened, which screens were viewed, and how long each interaction took. All of this is fully anonymous - we have no user accounts, no name, no email, and no way to identify you personally. Google receives your IP address on each request (as in any network call) and uses it only to determine country. We see aggregate numbers, not individuals.

2. Minimum-version check. Each time the app launches, we contact Firebase Remote Config (a Google service) and receive one value back - the minimum supported version. If your installed version is too old (for example, due to a halacha calculation bug that was fixed), the app will prompt you to update from the store. The request sends no personal data; it just receives a configuration value.

3. Silent pushes for widget refresh. Firebase Cloud Messaging (operated by Google) assigns your device a registration token on first install. We use this token to send a silent push twice a day asking the app to recompute widget data. The push itself contains no visible payload and does not appear in your notification center.

4. Anonymous crash reports. If something in the app crashes or hits an error, an automatic report is sent to Firebase Crashlytics (a Google service). The report includes your device model, operating system version, and what the app was doing when it crashed. It contains nothing that identifies you personally - no name, no email, no precise location. We use it only to know what to fix.

In all four of these, we do not know who you are. We have no user accounts, no name, no email, no phone number. Everything aggregates into statistical numbers, not individual users.

What we do NOT do

• We do not collect personal details: no name, no email, no phone number, no address.
• We do not display ads in the app and do not pass information to ad networks.
• We do not perform cross-app tracking or build advertising profiles.
• We do not sell data to third parties. Period.
• We do not share data with anyone other than Google's Firebase, described above.

Notifications

All scheduled reminders (up to 68 events per day) are scheduled and delivered by your device's operating system - iOS or Android - without our knowledge. We precompute the times and hand them to iOS/Android to fire at the appropriate moment.

Children

The app is age-rated 4+. It has no age-gated content, no user-generated content, no messaging features, and no social interaction. We do not knowingly collect any data from children.

Policy changes

If we update this policy, the date at the top will change. Material changes will be surfaced as an in-app notice.
