About
Peak State Apps is operated by Adrian Scheibelhut, an independent developer based in Germany. The studio focuses on small, focused tools that solve a specific problem and don't try to do more than that. Code for browser extensions is open source where it makes sense; mobile apps stay closed but never include third-party advertising or tracking SDKs.
Direct sales are handled through Lemonsqueezy; mobile apps are distributed through Google Play. Every customer email goes to one address, answered by the same person who builds the products — see Contact.
The privacy promise
Across every Peak State Apps product:
- No third-party advertising. No marketing trackers. No analytics on your usage of the apps themselves.
- No account creation required to use the products. Where licensing is involved, only your license key, your email (for delivery), and a per-install identifier are stored.
- We don't sell your data. Ever.
Per-product specifics are in the full privacy statement.
Contact
Bug reports, refund requests, privacy questions, business inquiries — all go to the same address. One person reads them; you'll usually get a reply within a couple of business days.
