Privacy policy.
Last revised 01 May 2026.
Sennasign collects only what it needs to run a lap — your email, your documents, the timestamps of your signings. Nothing is shipped to advertisers; nothing is tracked across the web.
What we collect
- Account credentials (email + hashed password)
- Documents you upload, for the duration of signing and retention
- Signing metadata: timestamp, IP, user-agent, location precision to city
- Sector telemetry: lap times, witness counts, jurisdiction tags
- Correspondence you send to Sennasign
What we do not collect
- We do not track you across the web
- We do not sell, rent, or share your data with advertisers
- We do not retain analytics cookies past the session
- We do not profile or scan the contents of your sealed documents
How long we keep it
Sealed laps are retained for ten years from the closure of the envelope — the statutory retention period for archival records. After that they are cryptographically shredded. Account metadata is removed within thirty days of paddock closure.
Where data lives
Primary operations are conducted from Boston. EU sub-processors are engaged for transactional email and timestamp authority where required by counterparties; those sub-processors are bound by standard data-processing agreements and are disclosed on request.
Data breach notification
In the event of a security incident affecting personal information of Massachusetts residents, Sennasign will notify affected individuals and the Massachusetts Attorney General in accordance with applicable Massachusetts data breach notification laws. Notification will be issued without unreasonable delay and within the timeframes required by applicable law.
Your rights
You may request access, correction, deletion or portability of your personal data by writing to contact@sennasign.com. Subject-access requests are answered within thirty days. You may also lodge a complaint with your national data protection authority.
