About
Make recordings with unbreakable proof of authenticity.
Every time you record with HashNote, it instantly seals your recording — before it even reaches your iPhone library.
What happens in the background ?
Step 1 — Tamper-proof Seal
Your recording is sealed with a unique digital fingerprint called a Hash. If even one byte changes, the seal breaks forever.
Step 2 — Blockchain Timestamp
The Hash is timestamped on the public blockchain. Don’t worry — it’s impossible to reconstruct your media from a hash.
Step 3 — Release recording to your Library
Even the creator can’t change a single thing, without breaking the seal.
Giving you solid technical proof of ownership, recording authenticity with time and date of capture.
If you decide to share your recording — anyone can verify its authenticity with free independent tools at www.hashscanner.io
