Privacy Policy - Sign PDF

Last updated: October 28, 2026

1. Introduction

EasyTech Agency ("we," "our," or "us") operates the Sign PDF mobile application (the "App", formerly called PDF Marmot). This page explains what the App does with your data. Sign PDF has no account and no sign-in. Your documents, signatures and details stay on your phone and are never uploaded to us.

2. Data that stays on your device

The following data is stored only on your phone, in the App's private storage. It is not sent to us or to any server:

• The PDF files you open, scan, create, sign, fill, combine, shrink or watermark, and the answers you type into them
• Your saved signatures and initials
• Your saved profile (name, address, phone, email), which the App proposes as the answer for matching blanks. You can edit or empty it in the Profile tab
• The App's settings

The App finds blanks in a document and recognizes text in scans (including the “Copy text” tool) with Apple's on-device vision technology. This processing happens on your phone. Nothing is sent for recognition.

3. Camera, photos and files

• Camera: used only when you choose “Scan a paper form”. iOS asks for permission at that moment. The pages stay on your phone. You can withdraw the permission at any time in iOS Settings.
• Photos: you pick photos with the system photo picker, which gives the App only the photos you select. The App does not read your library.
• Files: the App opens the PDFs you choose, or that another app sends to it, and saves to Files only where you tell it to.

4. Free documents counter

The free version includes a limited number of finished documents each month. The App keeps this counter in the iOS Keychain, on your device. It contains no personal data (only the month and the number of finished documents). Because the Keychain can survive the deletion of an app, the counter may still be there if you reinstall the App, so that reinstalling does not reset your free documents.

5. Product analytics

We use PostHog to understand how the App is used: which first-run choice is made, how many blanks were found in a document, which tool is opened, whether a document is finished, whether the subscription screen is shown and whether a purchase is made. Events are tied to a random identifier, not to your name, and they never contain your documents, the text you type, your profile, your signatures or file names. PostHog may also receive basic device information (device model, iOS version, App version, language). The data is processed on PostHog's servers in the European Union.

You can switch analytics off at any time with “Share anonymous usage counts” in the Profile tab of the App. See the PostHog Privacy Policy.

The App does not contain advertising and does not track you across other companies' apps and websites.

6. Subscriptions and payments

Pro subscriptions are managed entirely by Apple through the App Store. We do not have access to your payment information. We use RevenueCat to manage subscriptions: it receives an anonymous identifier and your subscription status and purchase history, nothing else. See the RevenueCat Privacy Policy.

7. Data sharing

We do not sell your personal information. The data described above is shared only with these providers, for the purposes described:

• Apple, for the App Store and subscriptions
• RevenueCat, to manage subscriptions
• PostHog, for anonymous product analytics (EU)
• Authorities, when the law requires it

When you share or export a document, it goes where you send it (for example Mail, Messages or Files). That is your choice and under your control.

8. Data security and backups

Your files are stored in the App's private storage with iOS file protection. We recommend a passcode and Face ID or Touch ID on your device. Like any app data, it may be included in the backups of your device that you make yourself (for example iCloud Backup or a computer backup), under Apple's terms.

9. Retention and deletion

Your documents, signatures and profile stay on your device until you delete them. You can delete a document in the App (press and hold it in the Documents list, or use its menu), delete a signature or empty your profile in the Profile tab, or remove everything by uninstalling the App. We hold no copy of your documents. To delete the data held by RevenueCat or PostHog about your anonymous identifier, write to us at the address below and we will act on it within 30 days.

10. Version 1.2 data

If you used PDF Marmot 1.2, the first launch of Sign PDF copies your documents and signatures from the old on-device storage into the new library, on your device. Nothing is sent anywhere and the old storage is left untouched.

11. Your rights

If you are in the European Union, the United Kingdom or Switzerland you have the right to access, correct, delete and port your data, to object to or restrict its processing, and to withdraw your consent at any time. Because your documents never reach us, you exercise most of these rights directly in the App. For the anonymous data held by our providers, write to us. You may also complain to your local data protection authority.

12. Children's privacy

Sign PDF is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, please contact us immediately.

13. Changes

We may update this privacy policy. Changes will be posted on this page with a new update date.
