Before You Write
Most questions are answered in the built-in help documentation. If you are using the web app or Android app, tap the ? icon or go to Settings → Help & Documentation.
- Forgot your key or salt? There is no recovery. Keys and salts are never sent to a server — only you have them.
- Can't decrypt a message? The key, salt, and mode (Standard vs Simple) must match exactly what was used to encrypt.
- Audio not working? Bring devices within 1 meter, reduce background noise, and switch to Normal protocol in Settings → Audio.
- HKPM requires Chrome or Edge. Firefox does not support the WebAuthn PRF extension used by hardware key mode.
- App works offline. After the first load, no internet connection is required for any feature.
Contact Support
For questions, feature requests, or anything not covered by the help docs, reach out directly.
Please include: what you were trying to do, what happened, your browser or app version, and your operating system. This helps resolve issues faster.
Response time is typically within a few business days. CipherBrick Pro is a solo project — there is no support team, but every message is read and taken seriously.
Send Email →Report a Bug
Bug reports are tracked publicly on GitHub. If you find something broken, opening an issue there is the fastest path to a fix.
Open a GitHub Issue →If you prefer not to use GitHub, email works too.
Security Reports
If you believe you have found a security vulnerability, please do not open a public GitHub issue. Report it privately by email so it can be assessed and addressed before public disclosure.
Please include a description of the issue and steps to reproduce.
Responsible disclosure is appreciated. There is no formal bug bounty program, but all genuine security reports are taken seriously and acknowledged.
Google Play — Refunds & Purchases
The Android app is available as a one-time paid purchase on Google Play. Google handles all payment processing and refunds.
- Refunds within 48 hours of purchase can be requested directly through Google Play
- For refund issues outside that window, contact Google Play support
- If you have a question about app functionality before purchasing, the full-featured PWA is available free at app.cipherbrick.com
The Play Store purchase funds hosting, domain costs, and continued development. It does not unlock additional features — the app is identical to the free PWA.
Privacy & Data
CipherBrick Pro has no accounts, no servers, and no data collection. If you have a privacy question, the answer is almost certainly covered in the Privacy Policy. The short version:
There is nothing stored on our end — because there is no "our end."
