Privacy Policy
Last updated October 28, 2026
1. Who we are
SignaraScan (“we”, “us”) makes the SignaraScan app for iPhone and Android. Questions about this policy or your data: support@signarascan.com.
2. Data that stays on your phone
Scanned pages, imported PDFs and images, your edits, the PDFs you save, your saved signatures and initials, and recently used fax numbers are stored in the app's private storage on your device. We cannot see them. Deleting a document or signature in the app deletes it from the device; deleting the app deletes all of it.
The camera and photo library are used only when you scan or import, and only the pages you choose are copied into the app. If you turn on signature protection, Face ID, fingerprint or your device passcode is checked by your phone's operating system; we never receive biometric data.
3. Sharing and exporting
When you tap Share or Export PDF, your phone's system share sheet or file picker sends the file to the app or place you choose. That app's own privacy policy then applies. We don't receive a copy.
4. Purchases and subscriptions
Payments are processed by Apple (App Store) or Google (Google Play). We never see your card or payment details. We use RevenueCat to check which plan you have. RevenueCat receives a random app user ID, your purchase receipts and, if you sign in, your account ID, so your plan and fax pages follow your account.
Your free trial start date is kept on your device (on iPhone, in the Keychain) so the trial isn't restarted by reinstalling.
5. Account (only for cloud backup and fax)
You only need an account to use cloud backup or fax. You sign in with Apple or Google. We receive an account identifier from that provider and the email address it shares with us (with Apple you can choose to hide your email). We use it to link your backups, fax history and fax page balance to you, and to send service emails such as a warning before backups are deleted. We don't send marketing email.
6. Cloud backup (Pro Cloud, off by default)
Only if you turn it on, we store in your private cloud space:
- your saved PDFs and the original page images;
- the placement data for your signatures, highlights and pen marks, so restored documents stay editable;
- document names and modification times;
- your saved signature templates — only if you separately switch that on.
Data is encrypted in transit and at rest. Access rules on the database and storage allow only your account to read your files. We don't look at, analyse or use your documents for any other purpose.
Retention. Backups are kept while you have Pro Cloud. If your Pro Cloud plan ends, backup stops and your cloud data is kept for 30 days so you can restore or export it; we email you 7 days before it is deleted. You can delete a single document's cloud copy, all cloud data, or your account at any time in Settings → Cloud backup.
7. Fax
A fax file is uploaded only after you review it and tap Send. To deliver it we process:
- the PDF being faxed, including any cover page you add;
- the destination fax number and, if you enter them, the recipient name, subject and note;
- the delivery status, page count and time.
The file is stored in a private storage area and handed to our fax carrier, Telnyx, through a link that expires after a few minutes. We delete the file within 7 days after the fax is delivered or finally fails, and ask the carrier to delete its copy. Unsent drafts are deleted after 1 day. Your fax history (number, page count, status, time) is kept for 1 year. If you delete a fax from your history it disappears from the app immediately; a minimal billing record is kept until the 1-year period ends.
Faxes can be sent only to numbers in the United States and Canada. SignaraScan is not designed for, and we do not claim, HIPAA compliance.
8. Notifications
If you use fax and allow notifications, we tell you when a fax is delivered or fails. This needs a push token for your device, which we store with your account. Notifications are relayed through Expo's push service to Apple Push Notification service or Firebase Cloud Messaging. Notification text names the fax status, not the document's contents.
9. Service providers

- No use of your documents or signatures to train AI models.
11. Your choices and rights
You can use the app without an account, keep cloud backup off, and delete documents, signatures, fax history, cloud data and your account in the app. Depending on where you live (for example under the GDPR or California law), you may also have the right to access, correct, export or delete your personal data, or to object to its processing. Email support@signarascan.com from the address linked to your account and we will respond within 30 days. You may also complain to your local data protection authority.
12. Children
SignaraScan is not directed to children under 13 (or the minimum age in your country), and we don't knowingly collect their personal data.
13. Changes
If we change this policy, we will update the date above, and for significant changes we will tell you in the app before they take effect.
