Privacy Policy

This policy explains how the Pythio Android app ("Pythio", "the app"), made by appalloo ("we", "us"), handles your information. Pythio teaches Python in short lessons. It asks you nothing about yourself: no account, no sign-up, no age, no goals.

1. What stays on your device

• Your progress: the lessons you finished or tested out of, the questions you answered wrong and haven't fixed yet, how well you know each question (a count of right answers in a row, used to pick what to practise), the day each lesson was last seen, your streak and streak freezes, the practice sets and stories you finished, today's challenge, and which idea cards and milestones you've already seen.
• Settings: whether you type mini-challenges or build them from tiles, the theme, sounds, and whether the daily reminder is on and at what time.
• The widget's puzzle: today's puzzle and the answer you tapped, so the widget can show it.
• The full course: whether it's unlocked on this device, as Google Play reports it (see section 3).

All of this is kept in the app's private storage, where other apps can't read it. None of it contains your name, contacts, location or anything typed into another app. "Start over" in Settings clears your progress; uninstalling the app removes everything.

Pythio allows Android's backup, so your progress and settings may be included in your device's backup and restored on a new phone. That backup is made and stored by Google under Google's privacy policy, in your own Google account; we can't read it.

2. Your certificate and "Send to my computer"

• Certificate: when you finish the course, Pythio draws a certificate on your device. You can add a name to it; the name is drawn into the image and never saved. The image leaves the app only if you tap Share, and then it goes to the app you pick.
• Send to my computer: this sends the steps for installing Python, a README.txt with the same steps, and the café's till you built in the course (main.py and menu.txt) to the app you pick in your phone's share sheet, such as your email or Quick Share. These files are made by the app from the course; they contain nothing about you.

3. Buying the full course

Part 1 is free. Parts 2 to 4 are opened by one optional in-app purchase.

• The purchase is handled entirely by Google Play, under Google's terms and privacy policy. We never receive your card or payment details.
• Pythio asks Google Play, through the Google Play app on your device, whether you own the full course, and keeps only the answer. This is the only time the app talks to another service on its own, and it goes to Google Play, not to us.
• Google Play gives developers order information, such as an order number, the date, the price paid and the country or region. We use it only to handle the order, refunds and taxes, and keep it only as long as the law requires.

4. Permissions

• Notifications (optional, Android 13 and later): for one daily reminder, if you turn it on in Settings. Pythio asks only then, never at first launch.
• Run at startup: to set the daily reminder again after your device restarts or its clock or time zone changes.
• Vibration: a short haptic when you finish a lesson or a unit. It asks you nothing.
• Google Play billing: to offer the full course through Google Play (see section 3).

Pythio doesn't ask for your location, contacts, camera, microphone or files.

5. The home screen widget

The Python puzzle widget shows a small question from lessons you've done, your answer, and your streak, on your home screen, where anyone holding your unlocked phone can see them. Answers on the widget count for nothing and are kept only for that day.

6. What other services see

• Apps you share with: when you share your certificate, use "Send to my computer" or "Share Pythio", the app you choose receives what you shared. That app's privacy policy applies.
• Google Play: processes the purchase and payment, and tells Pythio whether you own the full course (see section 3). Google's privacy policy applies.
• Your device's backup: may copy your progress and settings to your Google account (see section 1).
• Email: when you tap "Contact us", your email app opens with a message that includes the app version, Android version and device model, so we can help you. You can edit or remove them before sending.
• Links: python.org, code editors' websites, the Python tutorial, our privacy policy, terms and other apps open in your web browser or the Google Play app, only when you tap them. Those services' privacy policies apply.

7. When you contact us

If you email us, we receive your email address, your message and anything you attach. We use them only to reply to you and to provide support. We do not add you to mailing lists, and we do not share your message with anyone. Support emails are kept for as long as needed to help you and to keep a short support history, and then deleted. They are deleted sooner if you ask.

8. What we do not do

• We do not collect, sell, rent or trade your information.
• We do not show ads or use analytics or the advertising ID.
• We do not track you, in the app or across other apps and websites.
• We do not ask you to create an account, or ask your age, goals or anything else about you.

9. Your rights

Depending on where you live (for example in the European Union under the GDPR), you may have the right to access, correct or delete your personal information. Because Pythio sends us nothing, the only information we may hold is the emails you send us and, if you bought the full course, the order information Google Play gives us (see section 3). To use these rights, email us. For data held by another service listed above, contact that service.

10. Children

Pythio is a course for teenagers and adults and isn't directed at children under 13. We don't knowingly collect information from anyone, because the app doesn't send us any. If you believe a child has emailed us personal information, contact us and we will delete it.

11. Changes to this policy

If this policy changes, we'll update this page and the effective date at the top.
