Privacy Policy

This Privacy Policy explains what information Sign For Free (“we”, “us”) collects when you use our website and mobile apps, how we use it, and the choices you have. Our design principle is data minimization: we keep as little as the service needs to work.

Information we collect

• Account information. When you sign in with Google or Apple we receive your name, email address, and a unique account identifier from the identity provider. We store your profile (email, linked emails, language and timezone preferences, consent records, and settings).
• Documents and envelopes. PDFs you upload are processed to run the signing flow and are delivered to participants by email when signing completes. Server-side copies are automatically deleted after the signing flow completes or the envelope expires — we do not keep a long-term archive of your signed documents. Completed documents can be verified later without our servers using the built-in verifier.
• Recipient information. Names and email addresses of the people you invite to sign, which we use to deliver signing invitations and completion emails.
• Signature assets. In the mobile app, personal stamps and signatures you save are stored on your device in the operating system’s secure storage (iOS Keychain / Android encrypted storage). Signature images attached to a document are processed as part of that envelope and follow the envelope’s deletion lifecycle.
• Advertising identifiers (mobile app, free plan only). The app shows rewarded ads through Google AdMob. AdMob may collect device identifiers (such as the advertising ID) and ad-interaction data. On iOS, personalized ads are only enabled if you allow tracking in the App Tracking Transparency prompt; if you decline, ads are non-personalized and rewards work the same.
• Purchases. Paid upgrades are processed by Apple App Store or Google Play. We receive purchase receipts to activate your plan; we never see your payment card details.

How we use information

• To provide the signing service: creating envelopes, delivering invitations and completed documents, and verifying access.
• To operate your account: authentication, plan entitlements, and settings.
• To show ads in the free mobile app and to activate paid plans.
• To comply with legal obligations and prevent abuse of the service.

We do not sell your personal information.

Service providers

We rely on a small set of processors to run the service: Google Cloud / Firebase (authentication, database, storage, hosting), an email delivery provider (signing invitations and completion emails), and Google AdMob (mobile ads). These providers process data on our behalf under their own security and privacy commitments.

Retention

• Envelope documents: deleted automatically when the envelope completes or expires.
• Account profile: kept until you delete your account.
• On-device stamps (mobile app): stay on your device until you remove them or uninstall the app.

Your rights and choices

You can delete your account and associated data at any time from Settings → Delete account in the web app or mobile app. Deleting your account erases your envelopes (including in-progress ones, whose signature requests are voided), your profile, and your sign-in account. See How to delete your account for details. Depending on where you live, you may also have rights to access, correct, or port your data — contact us to exercise them.

Children

Sign For Free is not directed at children and is intended for users old enough to enter into agreements. Do not use the service if you are under 13 (or the equivalent minimum age in your jurisdiction).

International transfers

Our infrastructure runs on Google Cloud. Your information may be processed in countries other than your own; where required, we rely on our providers’ standard safeguards for such transfers.

Cookies

The website uses strictly necessary cookies and browser storage only — see the Cookie Policy.

Changes

We will post any changes to this policy on this page and update the date above. For significant changes we will provide additional notice in the product.
