Privacy for Every Formula and Batch
RatioForge is a focused formula workspace for balancing material ratios, scaling recipes for production, tracking batches, and keeping practical testing notes together. The app works without registration, and the information you enter remains on your device.
Information We Do Not Collect
RatioForge does not collect personal information, device identifiers, usage statistics, analytics, advertising data, precise location, contacts, photos, payment information, formulas, recipes, batch records, or testing notes. You do not need to create an account, sign in, or provide a user profile.
Your Production Records Stay Local
Material names, ratio values, recipe quantities, scaling calculations, batch details, results, costs, and testing notes are stored locally on your device. We cannot access, view, retrieve, or use these records.
On-Device Formula Tools
Ratio calculations, recipe scaling, batch summaries, and comparison views are generated within the app from information stored on your device. Your formulas and production records are not uploaded for remote processing. RatioForge is an organizational and calculation aid. Users remain responsible for verifying measurements, material compatibility, safety requirements, and final production decisions.
No Third-Party Services
RatioForge does not include third-party analytics, advertising networks, tracking technologies, social logins, cloud accounts, or external software development kits that collect data. We do not sell, rent, share, or disclose user information because we do not collect it.
Data Retention and Deletion
Your locally stored formulas, recipes, batches, and notes remain on your device until you edit or delete them, clear the app's data, or uninstall RatioForge. Depending on your iCloud and device backup settings, Apple may include app data in a backup. Those backups are controlled by you and Apple and are not accessible to us.
Security
Keeping formula and batch records on-device limits unnecessary exposure. You are responsible for protecting access to your device through the security features available in iOS.
Children's Privacy
RatioForge is not directed to children under 13 and does not knowingly collect information from children or any other users.
Your Privacy Choices
Because RatioForge does not collect or retain personal data on our systems, there is no personal information for us to access, correct, export, or delete. You control your formulas, batch records, testing notes, and device backup settings.
Changes to This Policy
We may update this Privacy Policy if RatioForge features or legal requirements change. Any revised version will be posted on this page with a new effective date.
