Absolute zero telemetry
Overwrite runs fully offline. It doesn’t track, collect, or transmit anything — no analytics, no crash reports, no phoning home. A privacy tool that spies on you isn’t a privacy tool.
The uncomfortable truth
Your Trash can is lying to you.
This is what the actual bytes on your drive look like after you “delete” something. Pick a method and see what a recovery tool would find.
The files just get unlisted.
Emptying the Trash only deletes the reference to your files. Every photo, tax return, and document stays physically on the drive until something happens to write over it — which can take years.

Certificate of ErasureCryptographically signed · generated locally
Built different
Engineered for paranoia.
Engineered for paranoia.
Designed for everyone.
No terminal. No jargon. Just serious data destruction wrapped in an interface your parents could use.
Forensic erasure certificates
Every wipe can generate a PDF Certificate of Erasure, signed locally with ECDSA keys. Selling a drive, returning company gear, or just want receipts? You have mathematical proof it’s clean.
Smart APFS safeguards
Read-only partition? Hidden volume snapshot lurking on the drive? Overwrite detects the traps that silently break other wipe tools and walks you through fixing them — before the wipe starts.
Automatic unmounting
Overwrite force-ejects the volume from Finder before a single byte is written, so nothing on your Mac can collide with the wipe mid-flight. You don’t think about it. It just works.
What’s new
Version 2.0 speaks your language. All ten of them.
Securely erased.English
Fully localized, fully native
English, Arabic, French, German, Italian, Japanese, Korean, Portuguese, Spanish, and Simplified Chinese — a complete native catalog, not machine-translated strings.
Universal accessibility
Full VoiceOver support, custom navigation triggers, and fluid text that never truncates. Built to WCAG and Apple HIG standards — secure erasure for every user.
Two slides. That’s it.
A streamlined linear onboarding gets you to your first wipe in seconds — and locks zero-telemetry preferences on first launch, so private is the default, not a setting.

Questions
Fair questions, straight answers.
Doesn’t emptying the Trash already delete my files?
No — it only removes the directory entry that points to them. The actual data stays on the drive until it happens to be overwritten by something else. Free recovery tools can restore “deleted” files in minutes. Overwrite replaces the data itself with zeros or random passes, which is why it’s unrecoverable.
Is overwriting safe for SSDs and SD cards?
Yes. For modern flash media, a single pass is generally sufficient because of wear-leveling algorithms — and Overwrite tells you exactly that in the app rather than pushing you to burn write cycles. Multi-pass standards (DoE, DoD, Gutmann) are there when policy or peace of mind requires them.
Can Overwrite wipe my Mac’s internal drive?
Deliberately, no. For your safety, the internal boot drive is protected and hidden — Overwrite is designed exclusively for external and secondary drives: USB sticks, SD cards, external SSDs and HDDs. You can’t accidentally nuke your Mac.
Does Overwrite send my data anywhere?
Never. Overwrite executes fully offline with absolute zero telemetry — no analytics, no tracking, no external servers. Even the erasure certificates are generated and signed locally on your Mac using ECDSA keys.
What exactly is a Certificate of Erasure?
A PDF report generated after a wipe that records the device, method, pass count, and result — cryptographically signed on-device. It’s proof of sanitization for buyers, employers, or auditors, aligned with the NIST 800-88 standard for media sanitization.
What happens if a drive is read-only or has APFS snapshots?
Overwrite detects read-only APFS partitions and hidden volume snapshots before wiping and guides you through resolving them, so you never end up with a wipe that silently didn’t stick.
Some files should stay gone.
