They sign. They see.
Stop sending naked links. Gate your intellectual property behind a fast, legally verifiable electronic signature. You get an audit trail; they get access.
2-Minute Setup · End-to-End Encrypted · eIDAS SES (EU No 910/2014) · GDPR-Native Infrastructure

A click-to-accept NDA + evidence trail.
Stop sending unprotected links. Require clients to accept one-click Evaluation Terms before they view your work, generating a reliable evidence trail without the heavy friction of a traditional NDA.
Create fast access terms →Without SignToSee
✗ "Here's my Figma link 🙂"
✗ No clear evaluation-only permission scope
✗ No verified acceptance event before access
✗ Weak or fragmented evidence if a dispute appears
With SignToSee
✓ "Access requires Access & Evaluation Terms (NDA-compatible)."
✓ Verified email + acceptance event before viewing
✓ Timestamped eIDAS-backed audit trail
✓ Exportable evidence package 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 fast legal access 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 terms (NDA-compatible) → key is revealed client-side only
→ 5GB EU-sovereign storage
→ Optional AES-256 payload encryption
→ Download audit trail + 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. Guardian goes up to 20GB — both with optional AES-256 payload encryption. Upload once, gate it with the same Access & Evaluation 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 evidence. 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 Audit Trail
When a recipient clicks Agree, we capture a Forensic 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.

Watermark, NDA, or Gated Access: Which One Should Freelancers Use?
A practical guide to what each method actually does, where it falls short, and when a combined workflow makes more sense.
How to send design concepts to clients before approval without losing control
Freelance designers often have to share previews, concepts, and client-facing files before trust is fully in place. Here’s an easy, more structured way to do that.
How Freelance Consultants Can Share Strategy Work Without Giving Too Much Away
When your thinking is the product, sending a deck, audit, or recommendation too casually can feel riskier than it looks. Here’s a more structured way to share early-stage consulting work.
