Privacy Policy
How the LCTR web tools handle your data. Short version: your files stay on your device.
Who we are
LCTR runs the free tools on apps.gzor.es. Contact: support@gzor.es.
Your files
The free tools, including the converters, the background remover and the PDF editor, run inside your browser. Your pictures, PDFs, audio and videos are not uploaded to us and we cannot see them.
Android apps
The LCTR Android apps (PNG to WEBP Converter, Background Remover Offline, PDF Compressor Offline) do everything on your phone. They have no internet permission, so nothing can be sent from the app. We collect no data: no account, no analytics, no advertising identifier, no crash reports. The app reads only the files you choose or share to it, and saves results to your Downloads folder. If you tap Share on a result, Android hands that file to the app you pick, and that app's own policy applies.
What we collect
No accounts, no sign-up, no advertising or tracking cookies. Our web server keeps standard access logs (shortened IP address with its last part removed, time, page, browser name). Logs are rotated daily and kept for about 14 days. We use them to keep the site running and secure, and to count page visits and clicks on our Store and Gumroad buttons, without scripts or cookies.
Passes
When you buy a pass we keep the Stripe checkout session id, the pass type and the time it was sold, in a small database on our server. We do not receive your name, email or card details. Your browser stores a signed pass token in local storage so the download works for 24 hours. We keep a session record for 13 months to handle refund and tax queries, then delete it.
Cookies and storage
We set no cookies. Your browser may cache the tool files and the background-remover model so the next visit is faster. You can clear this in your browser settings.
Third parties
The site is hosted on a server in Germany (Hetzner). Search engines may index the pages. Payments are handled by Stripe, which is the seller (merchant of record) and has its own privacy policy: https://stripe.com/privacy. We never see or store your card details.
Your rights
If you are in the EU, UK or California you can ask us what we hold about you, ask for a correction or deletion, and complain to your data protection authority. Write to support@gzor.es. We do not sell personal data and do not knowingly collect data from children under 13.
Legal basis (EU)
Server logs: legitimate interest in running and securing the site (GDPR Art. 6(1)(f)).
