Privacy Policy — Jewish Calendar

Last updated: July 28, 2026

Jewish Calendar is one of the Derekh Learning family of companion apps. It has no account and no sign-in. This page explains exactly what this specific app does — and does not do — with your information. For the company-wide policy covering our website, web app, and main iOS app, see the Derekh Learning Privacy Policy.

What Jewish Calendar collects

The only data type this app touches is your location, and only to calculate accurate halachic times (zmanim and candle-lighting) for where you are.

  • Your location is used only for app functionality (computing times).
  • It is not linked to your identity (there is no account) and is not used to track you.
  • It is not stored by us and is not shared for advertising.

Location is optional — the app also works with manual city or coordinate entry. Everything else about the app is Data Not Collected.

Where your data lives

Your personal dates (yahrzeits, Hebrew birthdays), settings, and saved location stay on your device. You can export/import them yourself as a backup file.

Services this app connects to

  • Hebcal (hebcal.com) — a public Jewish-calendar API, for Hebrew dates, holidays, and times. Requests are generic; no personal data is sent. When you enable location, your coordinates are sent to Hebcal only to return times for your area.
  • Derekh Learning content service — a read-only request that returns already-published, shared Torah content (a lesson, verse, or card). The request sends nothing about you.

Permissions

  • Location (When In Use) — "Your location is used only to calculate accurate halachic times (zmanim) for where you are. It isn't stored or shared." You can decline or revoke it in iOS Settings and use manual entry instead.

No accounts, no analytics, no ads

This app has no login and no user account. It contains no third-party analytics or advertising SDKs, and it does not track you across other apps or websites. There is no advertising identifier (IDFA) use.

Children's privacy

This app is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we will take reasonable steps to address it.

Data retention

Because this app keeps your information on your device, we do not hold it. Data stored on your device is removed when you delete the app (subject to any device or iCloud backups, which are under your control).

Your choices

You can manage any permissions this app uses (such as location or microphone) at any time in iOS Settings, and the app keeps working without them wherever possible. Deleting the app removes its on-device data.

Changes to this policy

We may update this page from time to time. When we do, we will change the "last updated" date at the top.
