TimeVault is “Undo” for your real files.

Ever edited a Word document, Excel sheet, PDF, or a folder of photos… then realized you overwrote something important? That sinking feeling is exactly what TimeVault is built to prevent. It quietly keeps previous versions so you can relax knowing you have a way back.

What problem does it solve?

Accidental overwrites (saving changes you didn’t mean to keep)

“I changed it yesterday and now I need the old copy”

Mistakes while editing documents, reports, invoices, study notes, or images

Peace of mind for important folders you choose (work, study, family photos)

What TimeVault protects (examples)

Images: JPG, PNG

Documents: PDF, Word (DOC/DOCX), Excel (XLS/XLSX/CSV), PowerPoint (PPT/PPTX)

Many other common file types (audio/video/archives) are also supported for versioning and restore

How it works (simple)

You select the folder(s) you care about (you stay in control)

Turn Protection ON (runs in the background with an ongoing notification)

When files change, TimeVault saves earlier versions on your device

Open “Previous Versions” for a file to view the timeline and restore an older copy

Restore with confidence

See a chronological list of versions (date/time + file size)

One-tap restore to roll back to a previous version

Image preview for image versions before restoring

Storage‑efficient by design

TimeVault is built to avoid “unlimited growth” and unnecessary duplicates:

Versions are stored locally and automatically managed

The app keeps up to 10 recent versions per file (older ones are cleaned up)

Total stored history is automatically capped (about 300 MB by default), so it won’t silently consume your phone storage

Extra safety cap: SnapshotManager.kt also skips versioning files larger than ~250 MB (MAX_FILE_BYTES = 250 MB), so huge videos etc. won’t be snapshotted.

Battery‑aware background protection

Protection runs only when you turn it ON

Scanning adapts automatically: it checks more frequently when there’s activity, and backs off when idle (and slows down when the screen is off)

You can turn Protection OFF anytime from inside the app or the ongoing notification

Private & offline

Your version history is stored locally on your device

No account required

Important note about deletion

TimeVault is designed mainly for “accidental changes/overwrites”.
If a file is deleted, restoring back to the original file may not always be possible (depending on Android storage/provider behavior).
