Reactive Wallpaper ("the App") is developed and operated by saither. This privacy policy explains what data we collect, why we collect it, how we protect it, and what rights you have over it.
We believe in minimal data collection. We only gather what is strictly necessary to deliver the product and process your purchase. We do not sell your data, we do not run ads, and we do not use tracking cookies.
We collect the minimum data needed to sell, deliver, and activate the software. Here is a complete breakdown:
| Data Point | What Exactly | When Collected |
|---|---|---|
| Email address | The email you provide at checkout | At purchase |
| Payment information | Card/payment details processed by our payment provider (we never see or store card numbers) | At purchase |
| Device identifier hash | A one way SHA 256 hash of your Mac's hardware UUID (the original UUID cannot be recovered from the hash) | At license activation |
| Serial number hash | A hashed representation of your license serial, stored on our server for activation verification | At license activation |
| Crash diagnostics | Crash metadata, stack traces, and technical context needed to debug failures, only if you enable crash reporting in the app settings | When the app crashes or reports an error |
What we do NOT collect: We do not collect your physical address, phone number, wallpaper content files, raw hardware identifiers for analytics, advertising identifiers, or any data from inside the App beyond what is listed above. Crash data is only sent if you enable crash reporting in the app settings.
| Data Point | Purpose | Legal Basis (GDPR) |
|---|---|---|
| Email address | Deliver your license key after purchase; send transactional emails (receipt, license recovery) | Performance of contract (Art. 6(1)(b)) |
| Payment information | Process your purchase securely through our payment provider | Performance of contract (Art. 6(1)(b)) |
| Device identifier hash | Bind your license to your device to prevent unauthorized redistribution | Legitimate interest (Art. 6(1)(f)) |
| Serial number hash | Verify license validity during activation | Performance of contract (Art. 6(1)(b)) |
| Crash diagnostics | Detect, investigate, and fix crashes when you choose to share crash reports | Consent |
We do not use your email for marketing unless you explicitly opt in. We will never sell, rent, or share your email address with third parties for advertising purposes.
To protect checkout and feedback forms from automated abuse, we use Cloudflare Turnstile, a privacy-respecting CAPTCHA alternative. Turnstile runs invisibly and may process limited browser signals (such as user agent and a Cloudflare-issued token) to confirm a request comes from a real visitor. See the Cloudflare Turnstile Privacy Addendum for full details on what is collected and how it is used.
We may update this privacy policy from time to time. When we make significant changes, we will:
We encourage you to review this page periodically. Your continued use of the App or website after changes are posted constitutes your acceptance of the updated policy.
