They sign. They see.
Stop sending bare links. Gate your intellectual property behind a fast, eIDAS-compliant digital access terms. You get an immutable audit log; they get access.
2-Minute Setup · End-to-End Encrypted · eIDAS SES (EU No 910/2014) · GDPR-Native Infrastructure
A click-to-accept access terms + immutable audit log.
Stop sending unprotected links. Require clients to accept one-click Standard Evaluation Terms before they view your work, generating a reliable access log without the heavy friction of traditional agreement workflows.

✗ "Here's my Figma link 🙂"
✗ No clear evaluation-only permission scope
✗ No verified acceptance event before access
✗ No verifiable access record if a question arises
With SignToSee
✓ "Access requires a Standard Access Terms before viewing."
✓ Verified email + acceptance event before viewing
✓ Timestamped eIDAS-backed access log
✓ Exportable access log when needed
Core Feature — Access & Evaluation Gating
We couldn't read your files
even if we wanted to.
Keep your files exactly where they belong - on Figma or Notion. We add a secure access control layer in front of them using zero-knowledge client-side encryption.
How it works
1. You paste your URL → we encrypt it in your browser
2. We store only an opaque ciphertext — never the plaintext
3. The decryption key lives in the URL fragment (client-only)
4. Recipient accepts Standard Workflow Access Terms → key is revealed client-side only
→ 5GB EU-sovereign storage
→ Optional AES-256 payload encryption
→ Download access log + CSV export
→ Immune to US CLOUD Act
Premium Upgrade — Secure File Hosting
Need to send a raw file?
Sentinel+ includes 5GB of secure, EU-sovereign file hosting. Upload once, gate it with the same access terms. Your raw file never touches a US data center.

by Design.
SignToSee is not just a gate — it is a mathematically verifiable sequence of access events. Keep control over what you share. Every interaction is logged, hashed, and sealed permanently in an isolated per-gate ledger.
Zero-Knowledge Encryption
The browser encrypts the file URL before it leaves the device. Our servers store only an opaque ciphertext blob. The decryption key lives exclusively in the URL fragment — technically unreachable by SignToSee or any third party.
- Algorithm
- AES-256-GCM
- Key scope
- Sender / Recipient only
- Server access
- None (zero-knowledge URL mode)
eIDAS-Compliant Access Log
When a recipient clicks Agree, we capture an Access Snapshot under EU eIDAS Regulation No 910/2014. Three data points are recorded atomically and sealed against retroactive alteration.
- IP Address
- Verified + logged
- Timestamp
- UTC — ms precision
- Fingerprint
- Browser fingerprint hash
Isolated Per-Gate Ledgers
Instead of a fragile global ledger, each Gate gets its own strictly isolated cryptographic hash chain. Every signature is linked only to prior signatures on that exact document. You can safely delete or archive a Gate without breaking the integrity of your other work.
- Hash function
- SHA-256
- Architecture
- Isolated Per-Gate Chains
- Output
- Verifiable audit log
Live Integrity Mockup // SHA-256 Hash Chain
Tamper-proof by design.
Our database uses a strict append-only ledger. If any actor — including a SignToSee engineer — attempts to retroactively alter a historical signature record, all subsequent hashes immediately invalidate.
