KIN52 e-Sign — Privacy Policy
Last updated: June 30, 2026
1. Overview
KIN52 e-Sign (“the App”, “we”, “us”) is an electronic signature and document workflow platform. This policy explains what information we collect, how we use it, and the choices you have. It applies to the App on the web, Android, and iOS.
2. Information we collect
- Account information — your name, email address, organization, role, and password (stored only as a secure cryptographic hash).
- Documents & signatures — files you upload, the signatures, initials, and form fields you or your recipients apply, and the resulting signed documents and signing certificates.
- Audit & security data — signing events, timestamps, IP address, and device/browser information recorded for the legal audit trail.
- Device information — on mobile, basic device identifiers and, only with your permission, access to your camera (to scan documents), Face ID / fingerprint (to unlock the app), and push-notification tokens.
- Optional integrations — if you connect Microsoft Office 365, we store the access tokens needed to provide that integration.
3. How we use your information
- To provide the core service: preparing, sending, signing, and storing documents, and generating signing certificates.
- To authenticate you and keep your account and documents secure.
- To send transactional emails and, if enabled, push notifications about documents that need your attention (e.g. signature requests, reminders).
- To maintain a tamper-evident audit trail required for legally valid e-signatures.
4. Device permissions (mobile)
The mobile app requests these permissions only when you use the related feature, and you may decline:
- Camera — to scan a paper document into a PDF for signing.
- Face ID / Touch ID / fingerprint — to unlock the app locally. Your biometric data never leaves your device and is never sent to us.
- Notifications — to alert you about documents awaiting your signature.
- Files — to open a document you share into the app for signing.
5. How information is stored and shared
Data is stored on managed cloud infrastructure. We share information only with service providers that help us operate the App — for example database and file hosting, and email delivery — and only as needed to provide the service. We may disclose information if required by law. Documents are shared with the recipients you designate for signing.
6. Data retention
We retain your account and documents for as long as your account is active or as needed to provide the service and meet legal, audit, and record-keeping obligations. You can request deletion of your account and associated data as described below.
7. Security
We use industry-standard measures including encryption in transit (HTTPS), hashed passwords, signed session tokens, and access controls. No method of transmission or storage is completely secure, but we work to protect your information.
8. Your rights
Depending on your location, you may have the right to access, correct, export, or delete your personal information, and to object to or restrict certain processing. To exercise these rights, contact us using the details below.
9. Children
The App is intended for business use and is not directed to children under 16. We do not knowingly collect information from children.
10. Changes to this policy
We may update this policy from time to time. Material changes will be reflected by updating the “Last updated” date above and, where appropriate, by notice in the App.
