Privacy policy.

Effective: 2026-10-20

1. Who is responsible and how to contact us

This notice covers FreePeriod for Android, package org.freeperiod.app, and this website. There is no developer-held copy of your in-app diary.

2. What is stored on your phone

The app stores what you choose to enter and the settings needed for the features you choose. Depending on what you use, this can include:

• Period dates and flow; mood, pain, symptoms, sexual activity, discharge and ovulation-test entries.
• Notes, tags, custom categories and items.
• Your chosen life phase and method, an optional pill-pack rhythm, usual cycle length and prediction preferences.
• Reminder titles, dates, recurrence rules and times, plus appearance, diary and app-lock settings.

These entries can reveal sensitive information about your health or sex life. They are stored in the app’s private local database (Room) and settings on your phone. Calendar estimates and summaries are calculated from your entries on the phone. You can leave optional fields empty.

FreePeriod is not a medical device. It is not a method of contraception and not a tool to help you get pregnant. It gives no medical advice, diagnosis or treatment. All dates, including days with a higher chance of pregnancy (on by default, can be switched off), are calendar estimates calculated on your phone from your own entries. They can be wrong and are not reliable.

3. What the developer does not receive

FreePeriod does not send your diary, settings or usage activity to the developer. There is no app server, account, advertising service, analytics SDK or crash-reporting SDK. The app has no internet permission and makes no network requests of its own. We do not sell your entries or use them for advertising or profiling.

The Google Play version lets you support FreePeriod with an optional one-time purchase that unlocks nothing. Google Play handles the purchase and the payment under Google’s privacy policy. For this the app contains the Google Play Billing Library, which talks to the Play Store app on your phone; FreePeriod only learns whether you have supported it. The library would bring a network permission for Google’s own diagnostics; FreePeriod removes it, so the app still has no internet access. The F-Droid version contains no purchase and no Google library.

Opening a website or choosing a file provider uses other apps on your device. Those apps may have internet access even though FreePeriod does not.

4. Backups, CSV files and moving to another phone

You can create or open encrypted backup files and export or import CSV files through Android’s system file picker. You choose the file and location. Backup files are protected with the password you choose; keep that password safe because the developer cannot recover it. If you leave the password empty, FreePeriod uses a fixed default password that is published in its source code, so anyone who gets such a file can open it. CSV files are readable text and are not encrypted by FreePeriod.

You can also import your period dates from an export file of another period app (for example a ZIP file that app sent you, with the password from its e-mail). FreePeriod opens and reads that file on your phone only; nothing is sent anywhere.

You can also turn on automatic backups: daily or weekly, FreePeriod writes an encrypted backup file into a folder you chose in Android’s folder picker and keeps the five newest. So that this can run in the background, the backup password is kept on your phone, sealed with a key from the Android Keystore. Turning automatic backups off removes it.

If you select a cloud folder, its provider app may upload or download the file under that provider’s terms and privacy policy. This transfer is handled by that app, not a FreePeriod server. Files you share with someone else are under their control after sharing.

The app’s Android backup rules exclude automatic cloud backup. On supported Android versions, Android can copy app data directly to a replacement phone during device setup. This is a system-managed device transfer; the developer does not receive the data.

5. App lock and reminders

Optional app lock adds a device-authentication step before opening the diary. Android handles device authentication; FreePeriod does not receive or store fingerprint or face templates.

Notifications are used only for reminders you configure and enable. Android handles notification delivery and permission. You can change or disable reminders at any time. You can choose whether period details appear in notifications, and Android’s settings control what is visible on your lock screen. App lock does not replace those notification settings.

6. Google Play and Android diagnostics

Google Play or Android may process their own crash and app-not-responding diagnostics, depending on their services and your settings. The developer may see diagnostic reports or statistics supplied by Google Play and use them to identify and fix faults. This is separate from an app-integrated crash-reporting SDK; FreePeriod contains none.

The app does not upload your diary to Google Play. Google’s platform processing is governed by Google’s privacy policy and the relevant device and service settings. We do not treat those platform statistics as a copy of your diary.

7. If you contact us or visit this website

If you email us, we receive your email address, message and any attachments you choose to send. Please avoid including diary entries or other sensitive information. We use correspondence to answer your request and keep it only as long as needed for the request, necessary follow-up or legal retention obligations.

This website is hosted on GitHub Pages. The host may process technical request data such as your IP address, browser details, requested page and request time to serve and secure the website. We do not add analytics, advertising trackers or tracking cookies. Fonts are served with the website; no external font service is loaded. See GitHub’s privacy statement for its processing and retention.

Where the GDPR applies, handling support requests, maintaining the website and investigating platform diagnostics relies on our legitimate interests in providing support and a reliable service (Article 6(1)(f)). Any retention required by law relies on Article 6(1)(c). None of this requires a developer-held health diary.

Hosting, email, Google services or a file provider you choose may process information outside the European Economic Area. Their applicable privacy information explains processing locations and transfer safeguards. FreePeriod itself does not transmit your diary to these services.

8. Retention and deletion

Your local diary remains on your phone until you edit or delete it, reset the app’s data or uninstall the app. Use Settings → Delete all data to remove the app’s local data. Uninstalling removes its private app data from that phone.

Exported CSV files, backup files, cloud-folder copies and data already copied to another phone are separate. Delete those copies from their locations if you no longer want them. Deleting the app cannot remove them. The developer cannot restore a deleted diary or remotely delete files held by you or another provider.

9. Your rights under the GDPR

Where applicable, you have rights of access, correction, erasure, restriction, data portability and objection to processing based on legitimate interests. You may withdraw consent at any time where processing relies on consent, without affecting earlier lawful processing. You can complain to a data-protection supervisory authority, particularly in the country where you live, work or believe an infringement occurred.

You can view and edit your entries in the app, obtain copies in its backup or CSV formats and delete local data as described above. The developer has no diary database to search, correct or delete on your behalf. You do not need to send us health information to exercise control over your local diary.

For requests about information we actually hold, such as an email you sent, contact support@jaysay.it. We will handle the request under the applicable rules and request identity verification only when needed. For information controlled by Google, the website host or your chosen storage provider, you can also contact that provider directly.

10. Ages 14 and up

FreePeriod is intended for people aged 14 and above, not children under 14. It has no account or developer-side diary collection. Local entries can be removed using the deletion controls above. Applicable rules for minors can differ by country; the stated audience is not a claim that one consent age applies throughout the EU.

11. Changes to this notice

We will update this notice when the app or relevant processing changes and change the effective date above. Material changes will also be highlighted through an appropriate release notice. You can always read the current notice here.
