1. Studio Philosophy
Zer0k7 Lab ("we", "us", or "our") designs applications with a local-first, privacy-respecting posture. We believe user data should belong exclusively to the user. We do not sell personal information, and we do not bundle invasive tracking or third-party behavioral profiling SDKs into our applications.
2. Application-Specific Policies
SubDebt Manager: SubDebt Manager operates as a 100% offline personal finance and liability tracker. The application requests zero network permissions in its Android manifest. All debts, contacts, receipts, and repayment ledgers remain strictly within your device's local encrypted SQLite database. No ledger data ever leaves your device.
ExamDock: ExamDock is an academic document repository. When you sign in with your Google Account, we receive your basic profile (display name, email, avatar) to authenticate paper uploads and sync favorites. Uploaded question papers are stored in Cloudflare R2 object storage and Firestore. We enforce strict 5MB file limits and client-side watermarking.
3. Web Portal & Community Hub
On our web portal (zer0k7lab.tech), accounts created to submit feature requests, cast roadmap votes, or enroll in beta testing store your name, email, device model, and preference flags in secure serverless databases powered by Neon PostgreSQL.
