Contracts, salary slips, medical reports, and college thesis drafts should never be uploaded to remote cloud servers. FileBase is designed from the ground up to protect your privacy.
No Google Analytics, no Mixpanel, no Facebook SDKs, no behavioral tracking. FileBase never phones home.
No registration, no password creation, no email harvesting. Open the app and read your files immediately.
Your files never touch external servers or third-party cloud buckets. Everything stays on your local Android hardware.
Password-protected PDFs are decrypted strictly in volatile RAM and instantly flushed when closed. Never written to disk unencrypted.
Any temporary print spool artifacts or render caches are purged automatically on app startup and session completion.
Only requests the storage read permissions strictly necessary to discover documents on your Android device.
“Why should opening, reading, and managing documents you already own require an internet connection, multiple paid subscriptions, and invasive telemetry? It shouldn’t.”
