PixGraph Terms of Use
Application-specific conditions, to be read together with the general Terms of Use.
2. Payments, restoration and refunds
Google Play handles purchases under its terms. A completed purchase can be restored using the same Google Play account on compatible devices. Pending payments do not grant paid access until confirmed. Refunds follow Google Play policies and applicable law; contact us for purchase problems. A refund may remove the corresponding paid entitlement. Uninstalling the app does not itself request a refund.
3. PixGraph
PixGraph digitizes charts and fits mathematical models. Results are estimates affected by image quality, calibration, selected points and model choice; verify them against the source before relying on them. Premium unlocks unlimited saved projects, CSV export and optional Google Drive backup and restore. Google Drive requires your authorization and is subject to Google's terms and availability.
4. Your content and privacy
You retain your rights to your images, projects, dates and exports. You must have permission to use and share imported content. Processing, permissions, storage and any optional sharing or backup are described in the relevant application's Privacy Policy.
5. Availability and responsibility
Keep independent backups before uninstalling, clearing app data or changing devices. Features may evolve, and operation depends on compatible devices and third-party services. We do not guarantee uninterrupted or error-free operation. To the extent permitted by law, we are not responsible for indirect losses. Nothing excludes liability, legal guarantees or remedies that cannot lawfully be excluded.
