You have the files, not the timeline.
A device or system date is changed in seconds. Sealway adds an independent qualified timestamp.
Compliant with the EU eIDAS Regulation
Give your files a timestamped, verifiable digital proof.
Photos, videos, audio recordings, PDFs, emails: Sealway produces an evidence file timestamped to the second by a qualified trust service provider, and verifiable independently.
A screenshot is no longer enough.
Editable photos, contested emails, files moved around: without reliable evidence, your version of events is fragile. Sealway documents what you have, what you sent, and when.
You sent an email, not the trace.
Sealway builds proof of sending and content integrity, verifiable by any third party.
You have the version, not the integrity guarantee.
A stable cryptographic fingerprint guarantees that the file you present has not been modified.
Sealway, your digital evidence file.

Three steps to produce an evidence file.
1. You select a file
In the Sealway app, capture a photo or video, or pick a file to certify. For emails, add Sealway in BCC when sending.
2. Sealway computes a fingerprint
Sealway receives your file, computes its fingerprint, then encrypts it before storing it according to your plan.
3. Qualified timestamp and evidence file
The fingerprint is timestamped by an eIDAS-qualified provider. You receive a PDF evidence file and a verifiable token.
European trust infrastructure.
Sealway relies on qualified trust service providers under EU Regulation 910/2014 (eIDAS).
Qualified timestamp
Timestamp token issued by a qualified provider, with legal effect across the EU.
European hosting
Data stored in the European Union. No transfer to a third country without a legal basis.
Independent verification
The token and fingerprint can be verified by any third party, without Sealway in the loop.
