Ratio Privacy Policy
Last updated: July 17, 2026
Overview
Ratio is designed as a local recipe ratio calculator. It does not require an account or collect your name, email address, Apple ID, or contact information. We do not sell or use your data for advertising.
Information Ratio Stores
Ratio stores your recipes, recipe and ingredient names, ingredient amounts, ratio values, app preferences, and processed recipe sticker images on your device so the app can remember your work and settings. This content remains in the app's private container. Deleting a recipe also deletes its locally stored sticker image when it is no longer used.
Data Collection
Ratio uses PostHog to collect limited product analytics, including app installs and opens, onboarding progress, screens and features opened, recipe selections and non-content counts, whether values were updated, app preference selections, and general technical information such as app version, iOS version, device type, locale, and time zone.
Analytics use random installation and session identifiers. These let us understand repeat usage but are not connected to your name, email, account, or advertising identity. We do not attempt to identify individual users. PostHog processes this information on our behalf under its privacy policy.
We use analytics only to understand how Ratio is used and improve the app. We do not sell analytics information or use it for advertising.
Recipe names, ingredient names, amounts, ratio values, selected or processed images, image filenames, and shared content are not included in analytics.
No Screen Recordings
Ratio does not record your screen, capture screenshots, record keystrokes, or use PostHog Session Replay. A screen-view event only indicates that a particular app screen appeared.
Photos and Image Processing
Ratio uses Apple's system photo picker when you choose an image for a recipe. The picker gives Ratio only the image you explicitly select; Ratio does not request broad access to or browse your photo library. Subject extraction and sticker rendering use Apple's Vision and image processing frameworks on your device. The selected source image is processed for this purpose, and the resulting sticker is stored in Ratio's private app container. Ratio does not send the source image or resulting sticker to Ratio-controlled servers.
Ratio does not request access to location, contacts, camera, microphone, or health data.
Sharing
If you choose to share content from Ratio using system sharing features, the information you share is handled by the apps or services you choose. Ratio does not receive or store information about where you share it.
Children's Privacy
Ratio does not knowingly collect personal information from children.
