Trough privacy policy
Last updated: 12 November 2026
Trough is a record-keeping app for people on prescribed testosterone treatment. This policy explains what happens to the information you put into it.
The short version
Your record stays on your phone. We do not receive it, we cannot see it, and we do not share it with anyone.
What Trough stores
Trough stores what you enter: your treatment details, doses, blood results, photos of lab reports, check-ins, weight, notes, questions and appointments. All of it is kept in an encrypted store on your phone.
What we collect
Nothing. Trough has no account, no sign-up, no analytics, no advertising and no tracking. The app does not send your record to us or to any other company.
Trough Plus
If you subscribe to Trough Plus, the purchase is handled by Apple through your Apple account. We do not receive your name, email address or payment details. The app asks Apple for the prices and whether your subscription is active, and nothing from your record is sent when it does.
Backups and sharing
You can make an encrypted backup file and save it wherever you choose. You can also share or print a summary, or export your record. These files go only where you send them. Once a file has left the app, it is covered by the privacy terms of the service or person you sent it to.
If you use your phone's own backup, such as iCloud Backup, your phone may include Trough's encrypted store in it. That backup is handled by Apple under your Apple account.
Permissions
- NotificationsFor dose reminders, if you turn them on. Reminders are scheduled on your phone.
- Camera and photosOnly when you choose to attach a photo of a lab report.
- Face IDOnly if you turn on app lock. Trough never sees your face data.
Deleting your information
"Delete everything", under Settings > Privacy and your data, removes your whole record from the phone. Deleting the app does the same. Files you have already exported are not affected.
Children
Trough is for adults who have been prescribed testosterone by a clinician.
Changes
If this policy changes, the new version will be published at this address with a new date.
