1. How MathIt works
MathIt is an educational math app for children and adults. Basic use does not require an account or contact details.
- Worksheets, archive, and settings are stored locally on the device.
- Worksheets are not synchronized between devices.
- The app does not display ads.
- The app does not use analytics or crash reporting.
2. What data we process
In normal use, the app stores data locally that is needed to operate, including worksheets, archive, and settings.
In the support form, we may process:
- report category,
- report subject and description,
- app version and build number,
- app language,
- platform and operating system details,
- selected UI settings when needed for diagnosis,
- optional email address if the user checked the consent box,
- optional screenshot if the user intentionally attached one.
3. Reports, email, and screenshots
Report
Submitting a bug report or suggestion is voluntary. Data only reaches us when the user intentionally fills in and sends the form.
Email is optional. It can be entered only after checking the consent box. We use it only to contact the user about the specific report.
Screenshot
A screenshot is optional and must be selected manually. It may contain worksheet content or other private information visible on the screen, so it should be checked before sending.
4. Purpose and legal basis
We process data only when it is necessary for app operation, handling the report, responding, diagnosing a problem, or meeting legal obligations.
- Art. 6(1)(b) GDPR - app operation and service delivery,
- Art. 6(1)(a) GDPR - optional email and optional screenshot,
- Art. 6(1)(f) GDPR - report handling, security, and app improvement,
- Art. 6(1)(c) GDPR - legal obligations when payments or accounting require it.
5. Recipients of data
Report data may be sent to Supabase and Supabase Storage. Supabase acts as the technical infrastructure provider for the report form and optional screenshots.
6. Ads, tracking, and diagnostics
MathIt does not use ads, analytics tools, or automatic crash reporting.
- we do not use advertising identifiers,
- we do not sell user data,
- we do not track user activity for marketing purposes.
7. Payments
Payments are handled by the app store, such as Google Play, Microsoft Store, or another store where the app is available. MathIt does not receive full payment card details.
8. Retention and deletion
- Worksheets, archive, and settings stay on the device until the user deletes them or uninstalls the app.
- Reports, optional email addresses, and optional screenshots are retained for a maximum of 12 months from receipt.
To request deletion of report data, contact us by email.
9. Security
Local data stays on the device, and its security also depends on the device's own protections. Reports are sent over HTTPS.
10. Children's data
MathIt is also intended for children. We design the app so basic use does not require an account, email, name, or surname.
If a child wants to send a report with an email address or screenshot, they should do so with help from a parent, guardian, or teacher.
11. User rights and complaints
Where provided by law, the user has the right to:
- access data,
- rectify data,
- erase data,
- restrict processing,
- data portability where applicable,
- object to processing,
- withdraw consent when processing is based on consent.
You can also write to the contact email.
12. Policy changes
This policy may be updated when app features, payment models, providers, or legal requirements change.
13. Data controller
The data controller is Kamil Kucharzewski.
