Privacy Policy

1. Overview

This policy explains what data Paper Plane Workshop (contact: paperplanecush@proton.me) collects on this website. Short version: as little as possible.

2. The calculators store nothing on our servers

All calculator math runs entirely in your browser. We do not send, see or store the numbers you enter. Your disclaimer acceptance and theme choice are stored only in your own browser (local storage) and never leave your device. We do not collect your date of birth.

3. Email you give us

If you submit your email for free content or updates, we use it only to send that content and occasional related updates. Unsubscribe anytime via the link in any email.

4. Purchases

Purchases happen on third-party platforms (Etsy, Payhip, Google Play, and similar), under their own privacy policies. We receive only what's needed to deliver your product and provide support.

5. Analytics

If analytics are used, they are privacy-friendly, cookie-free visit counting (e.g. Cloudflare Web Analytics). We do not run tracking cookies or sell data.

6. Our Android apps

Each app's data practices are described in its Google Play listing and in-app notices.

7. Your rights (GDPR)

If you are in the EU/UK you can ask us to access, correct or delete any personal data we hold about you, and withdraw consent at any time: paperplanecush@proton.me. We respond within 30 days.

8. Changes

We may update this policy; the date above shows the current version.
