A symptom diary with no account

Stored on your device and in your own iPhone backup. No account, no third-party servers. Here’s what that means in practice.

No account

You don’t sign up, log in, or give an email address to use Pera.

Where your entries are

Your entries are stored on your iPhone. If you use iPhone backup, they’re included in your own backup, like other app data. We don’t operate servers, cloud databases, or remote storage for your entries, so we can’t see them.

What leaves your phone

Your iPhone backup, if you use iCloud Backup, and whatever you choose to send. When you export the doctor report, the PDF is made on your phone and goes only where you choose to send it.

Subscriptions are bought through Apple. Apple processes the payment; we don’t receive your payment details.

If you delete the app

Deleting Pera removes its data from your phone. An iPhone backup you made earlier may still contain it. We don’t keep a copy.

This page describes the Pera app and how to keep a record of your symptoms. It is general information, not medical advice. For questions about your health, talk to your doctor.
