Archivr: Pack & Lock Archives

Archivr: Your Local & Private Archive Tool
Archivr is a fast, secure, and local-first archive tool for your Android phone or tablet. Manage your files with confidence, knowing they never leave your device. Pack, unpack, and password-protect your sensitive documents, photos, and videos without ever uploading them to a cloud service.

Open RAR & Encrypted 7z:
* RAR reader: open and extract RAR archives (RAR4 & RAR5) right on your device — read-only, no cloud needed.
* 7z with AES-256: create and unpack password-protected 7z archives secured with strong AES-256 encryption.
* Encrypted ZIP too: the same AES-256 password protection is also available for ZIP archives.

Powerful Archiving Features
Get full control over your archives:
* Pack Files: Create new ZIP, 7z, TAR, or TAR.GZ archives from your device's files.

Privacy-First Design
Your privacy is our top priority. Archivr is built from the ground up to be local-first:
* On-Device Processing: All compression, decompression, and password operations happen exclusively on your phone or tablet.
* No Cloud Uploads: Your files are never sent to our servers or any third-party cloud service.
* No Accounts, No Logins: Start using Archivr immediately without creating an account or providing personal information.
* No Tracking: We don't track your file contents or personal usage data.

Why Choose Archivr?
* Local & Private: Keep your sensitive data secure and offline.
* Fast & Efficient: Optimized for mobile devices to handle archives quickly.
* Easy to Use: A beautiful, modern interface with light and dark themes makes archiving simple.
* Share Anywhere: Seamlessly integrate with your device's share sheet to move files to local storage, email, or messaging apps.

How Archivr Protects Your Privacy:
* Files & Archives: All content is processed solely on your device.
* Passwords: Passwords are used only during the operation and immediately cleared from memory.
* Local History: A private history (up to 50 operations) stores metadata like filename, format, size, and date – never passwords or file contents. This is editable in settings.
* Crash Logs (Sentry): Anonymous crash reports help us improve the app, containing no user-identifying data or file content.
* Optional Ads: Archivr is free with non-personalized ads (Google AdMob). Remove ads permanently with a one-time Lifetime Premium purchase or a yearly subscription.
* Tip Jar: Support independent development with a purely optional thank-you contribution.
