A period tracker that doesn't sell your data
Period dates, pregnancy weeks and symptoms are some of the most personal things you can type into a phone. This is what Her Good Days does with them, in plain words, with the policy linked for every point.
Her Good Days does not sell or rent your data, shows no third-party ads, and contains no advertising or analytics code from other companies. As a guest, your logs never leave your phone.
With an account, logs sync to a separate health database kept apart from your email and from the shop. You can export them or delete your account from the app at any time.
- Keep a guest's logs on the phone only
- Sync an account's logs over HTTPS to servers in the United States
- Store health logs in their own database, apart from your email and the shop
- Encrypt backups and overwrite them after 6 months
- Count which features get used, without the values you logged
- Sell or rent personal data, or share it for advertising
- Show ads, or add advertising, attribution or analytics code from other companies
- Use health logs for marketing or to pick products for you
- Put health details in a notification
- Let staff read health logs as routine work
What "usage statistics" means here
The app may only send events from a fixed list, and the server drops anything else. Saving a sleep log is counted as "a sleep log was saved". The hours you slept, your answers and anything you typed never travel with it.
How long things are kept
| Data | Kept until |
|---|---|
| Account and health logs | You delete your account |
| Usage events | 25 months after they were recorded |
| Backups | Up to 6 months, then overwritten |
| A sign-in you stop using | One year |
What the app does not ask for
No location, contacts, photos, camera or microphone. If you connect Apple Health or Health Connect, the app asks first and reads only what you allow.
Export or delete
You can download everything you have logged, and close your account in the app under You, then Delete account. You can also ask from the website on the delete your account page. Your health logs are erased from our server the moment the account is deleted.
The full details, including the companies that host and deliver email for us, are in the privacy policy. If you wonder how an app like this pays for itself without your data, here is the answer.
Questions
Can I use the app without an account?
Yes. As a guest, everything you log stays on your phone and never reaches our server. An account adds sync and keeps your history when you change phones.
Does Her Good Days sell period tracking data?
No. We do not sell or rent personal data, share it for advertising, or use your health logs for marketing.
What happens when I delete my account?
Your health logs are erased from our live database at once, together with your email and name. Encrypted backups roll over within 6 months.
Do notifications show what I logged?
No. Lock-screen text is the same for everyone, for example "Your weekly summary is ready."
