4. Data Sharing and Third Parties
We do not sell your personal data. We share data only as follows:
4.1 Service Providers (Data Sub-Processors)
We engage the following carefully vetted third-party processors who process data solely on our documented instructions:
- Payment Processing — Stripe, Inc. (United States): Processes payment card details, billing addresses, and subscription invoices under PCI-DSS Level 1 compliance.
- AI Document Analysis (Opt-In SignLab AI Features Only) — OpenAI, L.L.C. (United States): When a Customer explicitly invokes an AI feature (AI Smart Prepare, AI Document Summary & Check, or Extended AI Legal Review Brief), transiently extracted document text wrapped in an isolated
<untrusted_document>sandbox is transmitted over TLS 1.3 to the OpenAI Enterprise/Platform API withstore: false(Zero Data Retention). OpenAI does not store the document text after generating the structured JSON response and never uses Customer Data to train or improve AI models. If you do not invoke SignLab AI Features on a document, zero document text is transmitted to OpenAI. - Document & File Object Storage — Backblaze, Inc. (EU/EEA by default; US available on request): Stores AES-256 encrypted PDF documents and signature assets in region-pinned buckets (Amsterdam, Netherlands EU region by default).
- Application Hosting Infrastructure — Hetzner Online GmbH (Finland / Germany, EEA): Provides dedicated European cloud server infrastructure, isolated local PDF text extraction (
poppler-utilsin a network-isolated--no-envprocess), and temporary encrypted storage for EU-region signed documents until object-storage upload is verified. - Content Delivery, DNS & WAF Security — Cloudflare, Inc. (Global Edge Network / US-incorporated): Proxies web traffic, terminates TLS 1.3, mitigates DDoS/bot attacks, and processes connection metadata (such as IP addresses).
- Transactional Email Delivery (EEA Processing Region): Delivers signature invitations, reminders, 2FA verification codes, and completion certificates to the email addresses you supply.
Full sub-processor details and international transfer mechanisms are published in Schedule 2 of our Data Processing Agreement (DPA).
4.2 Legal Disclosure
We may disclose personal data to law enforcement, courts, or regulatory authorities if required by applicable law or a valid legal order. Where permitted, we will notify affected users before disclosing their data.
4.3 Business Transfers
If SignLab is acquired, merged, or undergoes a change of control, personal data may be transferred to the successor entity subject to the same or equivalent privacy protections.
5. International Data Transfers
SignLab is based in the UAE. If you are located in the EU, EEA, or UK, your personal data may be transferred to and processed in countries that do not have an equivalent level of data protection. We ensure appropriate safeguards are in place including:
- Standard Contractual Clauses (SCCs) approved by the European Commission for transfers to US-incorporated processors such as Stripe
- Binding data processing agreements with all third-party processors
By default, SignLab stores documents and uploaded files in the European Economic Area (EEA), so documents belonging to EU/EEA customers remain within the EEA. US-based storage is available on request for customers who prefer it. Our storage provider is US-incorporated, so SCCs remain in place with it as a safeguard. If data residency in a specific region is a requirement for your use case, please contact us before using the Service.
Cross-Border Transfers for Opt-In AI Features (UAE PDPL Arts. 22–23 & GDPR Chapter V):
While primary document storage remains pinned to the EEA by default, invoking an optional SignLab AI Feature transmits
sanitized document text to OpenAI, L.L.C. in the United States for real-time inference only (with store: false
Zero Data Retention). These transfers are governed by European Commission Standard Contractual Clauses (SCCs, Module 2/3)
and UAE Federal Decree-Law No. 45 of 2021 (UAE PDPL) cross-border safeguard provisions. Customers who require zero cross-border
AI inference may disable SignLab AI Features at the company account level.
6. Data Retention
Temporary encrypted copies of EU-region signed documents are removed from the application server once their upload to object storage is verified. This normally takes about one minute plus upload time; during an outage, a pending copy is retained until upload succeeds or the document is deleted.
We retain personal data only for as long as necessary for the purposes set out in this policy:
- Account data: Retained for the life of your account plus 90 days following account closure
- Signed documents and audit trails: Retained for the duration of your subscription plus 30 days after cancellation
- Signer data (non-account holders): Retained as part of the signed document and audit trail for the document's full retention period
- Payment records: Retained for 7 years as required by UAE financial regulations
- Support communications: Retained for 3 years
- Backup copies: residual copies of deleted documents and files may persist in encrypted, access-restricted off-site backups for up to 92 days after deletion, after which they are purged
Important Note on Deletion Requests
Signed documents form part of a legal record. A request from one party to delete a signed document may affect the rights of other parties to that document. In such cases, we may not be able to fully comply with a deletion request. We will explain our position in writing if this applies to your request.

In the event of a personal data breach, we will notify affected users and relevant authorities as required by applicable law.
9. Cookies
SignLab uses strictly necessary cookies required for the operation of the Service (session management, security tokens). We do not use third-party advertising or tracking cookies without your explicit consent. A full cookie notice is available at signlab.app/cookies.
10. Children's Privacy
The Service is not directed at individuals under the age of 18. We do not knowingly collect personal data from minors. If we become aware that a minor has provided personal data, we will delete it promptly. If you believe a minor has used our Service, contact privacy@signlab.app.
