Privacy Policy

Overview

This policy explains how Cron Lab, an Android app made by Jake Haas, handles your information. The short version: Cron Lab does not collect, store, transmit, or share any personal information.

Information I collect

None. Cron Lab has no user accounts, no analytics, no advertising, and no tracking of any kind. I do not receive any personal information about you or how you use the app.

Cron Lab works completely offline. Your expressions, saved schedules, and settings live on your device, and the app's own code makes no network requests — there is no server, no sync, and no account.

Backups are files you control. Exporting your library writes a JSON file wherever you choose, and sharing an expression uses the system share sheet. Neither sends anything to me. The home-screen widget reads the same on-device data as the app.

The one component that talks to the internet is Google Play Billing, which handles the optional one-time Pro purchase (it is also why the app technically carries the network permission — the billing library brings it along). Google processes purchases under Google's own privacy policy; I never see your payment details.

The app requests nothing personal: no location, no contacts, no camera, and no access to your files beyond the backups you explicitly save or open.

Third-party services

Cron Lab does not embed third-party analytics, advertising, or tracking tools, and it does not share data with anyone — there is nothing to share.

Any purchase — the app itself or anything inside it — is handled by Google through Google Play. Google processes the payment under Google's own privacy policy; I never receive your payment details.

Children's privacy

Cron Lab does not knowingly collect information from anyone, including children under 13 — because it does not collect information at all.

Changes to this policy

If this policy ever changes, I will post the new version on this page and update the date shown above.
