Pro provides permanent access to the purchased local features. Separately offered future products or cloud services are not included. Google Play handles purchases and restoration; verified Pro works offline. Read the purchase terms.
How Free, Pro and your data work.
Yes. Free has no time limit and includes calculations, undo/redo, all three memory slots, all retained history up to 1,000 entries, history import/export, two workspaces, three templates and six everyday tools. There are no ads in Free or Pro.
Pro is an optional one-time purchase with no automatic renewal. It unlocks up to eight workspaces, up to 1,000 templates, all 17 current tools, extra themes and formatted PDF reports. The current local price and applicable taxes are shown by your app store before you confirm. You can keep using Free without buying Pro.
Pro gives permanent access to the purchased local Pro features, with regular updates included. It does not promise every future product or separately offered cloud service. Purchased local features will not be moved behind a subscription. See the Terms of Use for the purchase conditions.
Calculations and local tools work offline. Google Play handles Android purchases and restoration. After a purchase is verified on your device, Pro works offline without a daily online check. The app refreshes owned purchases through Google Play; refunds with revocation can remove Pro when the store updates its purchase list. Store caches can delay this update.
Use Restore Purchases in the app with the same Google Play account used to buy Pro. Connect to Google Play when restoring on a new device or after reinstalling. No Ryft account or Ryft verification server is needed. Purchases belong to their original store; a Google Play purchase does not promise Apple access. The iPhone version is planned.
No. On Android, the app verifies Google-signed purchase data locally using the app public licensing key. Purchase receipts, signatures and tokens are not sent to a Ryft verification server. Google Play processes billing under its own policies. Calculations, history, formulas, notes and tool inputs stay on your device unless you choose to export or share them. The Privacy Policy also explains website requests.
Yes. CSV, JSON and text history exports are free, and CSV/JSON history imports are free. Imports accept files up to 5 MB, merge valid records and keep the newest 1,000 entries. This transfers calculation history, not a full backup of workspaces, templates or settings. Formatted PDF reports are a Pro feature.
Refund requests follow the store process and applicable consumer law. A refund with revocation can remove Pro when Google Play updates the owned-purchase list. This update may be delayed by store caching and does not happen immediately while offline. Saved data is retained: reading and ordinary history export remain free, while Free limits apply to workspaces and creating new content. See the Terms of Use for details.
Ryft Calc is available for Android on Google Play. An iPhone version is planned; there is no iPhone download available here yet.
