Privacy Policy — Cykie

Last updated: 4 November 2026

Cykie (“the app”) is a period and cycle tracker developed by Tarik. Your privacy is the foundation of the app. This policy explains, in plain language, how your information is handled.

The short version

Cykie does not collect, transmit, sell or share any of your data. Everything you enter stays on your device.

What data the app stores

Cykie lets you record information such as your name (optional), cycle details, period days, symptoms, moods, and other daily notes. All of this is stored locally on your device in the app’s private storage.

How your data is used

Your data is used only on your device, to:

• calculate your cycle predictions, fertile-window and ovulation estimates;
• draw your calendar, insights and charts;
• schedule the local reminders you choose to enable.

What is NOT done with your data

• It is never uploaded to any server or cloud.
• It is never shared with the developer or any third party.
• It is never sold or used for advertising.
• The app contains no analytics or tracking software.
• The app makes no network requests to send your information anywhere.

Update check

Every few days, Cykie asks the store whether a newer version is out, so it can tell you an update is ready. On iPhone this is a single request to Apple's public App Store lookup that contains only Cykie's App Store ID. On Android, Google Play answers through the Play Store app. No health data, settings or identifiers are sent. You can turn this off in Settings › Privacy › Check for updates.

Notifications

Reminders are scheduled and delivered entirely on your device using the operating system’s local notification system. No notification content leaves your phone.

Permissions

Cykie may request permission to show notifications (so reminders can appear). This is optional and can be turned off at any time in the app or your device settings.

If you turn on Face ID or fingerprint unlock, the check is done entirely by your phone's operating system. Cykie only learns whether it succeeded — it never sees, stores or transmits any biometric data.

Files you choose to share from the app (a backup, a spreadsheet, a calendar file, your yearly story image or a summary for your doctor) are created on your device and only go where you send them.

Your control over your data

• You can export a copy of your data at any time from Settings.
• You can delete all data permanently at any time from Settings.
• Uninstalling the app removes all of its data from your device.

Children

Cykie is not directed at children and does not knowingly collect information from anyone, as it does not collect information at all.

Changes to this policy

If this policy changes, the updated version will be published at the same location and the “Last updated” date above will change.
