Privacy Policy
Last updated: March 15, 2026
Introduction
ProcessFlow, Inc. ("we", "our", or "us") operates the Signature Maker mobile application (the "App"). This Privacy Policy explains how we collect, use, and protect your information when you use our App.
Data Collection
Camera Access
The App uses your device's camera for signature scanning and document scanning. Photos taken within the App are processed locally on your device and are not uploaded to any server.
Local Storage
All documents, signatures, and files you create or import are stored locally on your device. We do not have access to your documents and do not upload them to any cloud service.
AI Document Review
When you use the AI Document Review feature, the text content of your document is sent to our servers for analysis by our AI service. This text is used solely to generate the review results and is deleted immediately after processing. No document files, images, or signatures are transmitted β only the extracted text necessary for the review.
Third-Party Services
We use the following categories of third-party services:
- Analytics provider β Anonymized usage analytics and session data to help us improve the App experience. No document content or personally identifiable information is collected.
- Error monitoring provider β Anonymized crash reports to help us identify and fix bugs. No document content or personal data is included in reports.
- Subscription management provider β Processes in-app purchases through Apple's App Store and Google Play. We do not collect or store payment information directly.
Advertising & Attribution
With your consent, we share anonymous app events (such as subscription purchases and feature usage) and your device's advertising identifier with advertising partners to measure the performance of our ad campaigns. No document content, signatures, or personal information is ever shared with advertising partners. If you decline consent when prompted, no data is shared with advertising partners β only first-party analytics will run. You can change your preference at any time in the App settings or through your device's privacy settings.
No Sale of Personal Data
We do not sell, rent, or share your personal information with third parties for their own marketing purposes. We do not create user accounts and do not require registration.
Children's Privacy
Signature Maker is rated 4+ (iOS) and Everyone (Android). The App does not knowingly collect any data from children. Since the App stores all data locally and does not require accounts, no personal information from any user β including children β is collected or stored on our servers.
Data Deletion
Your documents and signatures are stored locally on your device. You can delete them at any time within the App or by uninstalling. Text sent for AI Document Review is deleted immediately after processing and is not retained on our servers.
Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this page. Your continued use of the App after any changes constitutes your acceptance of the updated policy.
