Privacy policy

Short version: our apps don't collect personal data, and this website doesn't use cookies or analytics.

Last updated: 14 November 2026.

Our apps

Each app's own page lists exactly what it does. Our flashcard app, Premed Cards, works this way:

• No account, and it works offline.
• Your progress is stored only on your device. It is included in your device's own backups (iCloud or computer), if you have turned those on; we can't access those backups.
• No ads, no analytics and no tracking, and it doesn't send your data to us or anyone else.
• Deleting the app deletes its data from your device.

Apple may give us anonymous, aggregated statistics (such as downloads and crash reports) from people who have agreed to share them with app developers. These don't identify you.

This website

This website sets no cookies and uses no analytics. It is hosted by Cloudflare, which processes technical data such as IP addresses to deliver the pages and protect the site against abuse.

When you email us

If you write to us, we receive your email address and whatever you choose to include. We use it only to reply and to improve our apps, we don't sell or share it, and we delete it on request.

Children

Our apps don't collect personal data from anyone, at any age.

Your rights

Wherever you live, including in the European Union under the GDPR, you can ask us what we hold about you (usually nothing beyond emails you sent us), and ask us to correct or delete it, at contact@ptolemuscorp.com.

Changes

If this policy changes, we'll update this page and its date. If an app ever starts handling data differently, its page will say so before the change ships.
