Privacy policy
Last updated: August 23, 2026
Flowy stores the account identifier you choose (email address, phone number, Apple, or Google identity), the onboarding/profile details you provide, cycle and symptom entries, notes, preferences, and any profile image you upload. We do not require every optional field.
We use this information to authenticate you, sync your records, show and update your cycle calendar, calculate clearly labeled estimates, schedule local reminders, provide exports and deletion controls, prevent abuse, and respond to support requests.
Flowy uses PostHog to measure privacy-safe product events such as app opens, screen visits, onboarding steps, sign-up progress, and feature actions. Flowy uses Sentry for crashes, errors, performance traces, app hangs, and a breadcrumb trail of those same product actions so we can diagnose failures. We do not send names, contact details, cycle answers, symptoms, notes, health values, or calendar dates in analytics events, and session replay is disabled in both services.
This website is separate from the Flowy app. We partner with Microsoft Clarity to capture how you use and interact with our pages through behavioural metrics, heatmaps, and session replay, so we can spot confusing layouts and broken flows and improve the site. This usage data is captured with first- and third-party cookies and other tracking technologies. We also use the Meta pixel to measure our advertising. Neither loads until you accept them in our cookie banner, and you can change or withdraw that choice at any time through the cookie settings link in our footer. Vercel Analytics counts page views in aggregate without cookies and runs regardless. These website tools have no access to your Flowy account, cycle records, symptom entries, or Apple Health data. For more information about how Microsoft collects and uses your data, see the Microsoft Privacy Statement.
Apple Health is optional. With your explicit permission, Flowy reads only the selected menstrual flow, basal temperature, cervical mucus, and sleep samples and syncs typed records to your private Flowy account. Flowy does not write data to Apple Health. You can change Health access in iOS at any time.
We do not sell personal or health data. Supabase provides authentication, database, server functions, and private image storage. RevenueCat receives your account identifier and available contact profile details (email address, display name, and phone number) and processes subscription and purchase status. Apple processes purchases, while Apple and Google process their respective sign-in methods. PostHog provides product analytics, and Sentry provides error and performance monitoring. Microsoft, Meta, and Vercel receive website usage data from our marketing site as described under Website analytics. These providers receive only the information needed to provide their service under their own terms and privacy commitments.
Canonical account data is stored in Supabase with owner-scoped access controls, and sensitive local caches use iOS file protection. We retain account and health records until you delete them or your account. Requested export files are protected and automatically removed from temporary app storage after 15 minutes or when you leave the export screen. Limited billing event records may be retained for fraud prevention, accounting, dispute handling, and legal obligations; Apple keeps its own purchase records.
In Flowy you can correct past entries, export your data, or reset health data while keeping your account. A health reset removes health onboarding answers, cycle setup and history, imported Apple Health observations, reminder choices, predictions, and hidden health-chat history; it keeps authentication, profile identity and image, general app preferences, media, and subscription status. You can also permanently delete your account and owned data, disable notifications in iOS, disconnect Apple Health, manage or cancel subscriptions through Apple, and contact us for access or privacy questions.
Cycle and fertile-window dates are estimates based on the information available to Flowy. They are not a diagnosis, medical advice, or birth control. Manual tracking remains available when Apple Health access is declined or unavailable.
