Don't trust us — verify it yourself.
An Opviva record is only as good as your ability to check it. Paste an exported session below and confirm its hash chain is intact — recomputed from scratch on your own device, with no account and nothing uploaded.
How verification works
Export a session
From the dashboard, export any recorded session as a signed JSON bundle — it carries every event with its hash and prev-hash link.
We recompute the chain
Each event is hashed as sha256(prevHash + the canonical event). Alter or delete any event and its hash — and every hash after it — stops matching.
Nothing leaves your device
The whole check runs in your browser with the Web Crypto API. The bundle is never sent to Opviva or anyone else.
Want a record worth verifying?
Opviva's Flight Recorder captures everything your app and its AI agents do into a tamper-evident, reconstructable trail — exportable for any auditor, insurer, or regulator.
