Privacy Policy
This Privacy Policy explains how PainFlow handles personal, health, and wellness information when you use the PainFlow mobile application and related website.
1. Who we are
PainFlow is a personal health and wellness tracking application designed to help users record pain patterns, symptoms, flare-ups, routines, and notes for their own awareness and care conversations.
For privacy questions or requests, contact us at hello@painflow.app.
2. Information we collect
Depending on the features you use, PainFlow may process the following categories of information:
- Health and wellness entries, such as pain intensity, pain location, symptoms, flare-ups, medication notes, activity, sleep, triggers, routines, journal notes, and related timestamps.
- Contact information, such as your email address, if you contact support or send us feedback.
- Subscription information related to Premium purchases, such as product type, subscription status, renewal or expiration dates, and transaction identifiers provided by Apple. Payment details are processed by Apple, not by PainFlow.
- Website language preference cookie, painflow_language, which stores the language selected or detected for the website for up to 1 year so pages can open in the preferred language. This is a functional cookie and is not used for advertising or cross-site tracking.
- App usage and diagnostics, such as crash reports, device type, operating system version, app version, performance logs, and basic interaction events used to keep the app reliable and secure.
- Communications you send to us, including support messages and feedback.
3. How we use information
We use information only to operate and improve PainFlow, including to:
- provide tracking, history, and insight features inside the app;
- unlock and manage Premium features purchased through the App Store;
- remember the website language preference;
- respond to support requests and product feedback;
- maintain security, prevent abuse, and fix bugs;
- understand aggregate product performance and reliability.
4. Legal bases for processing
For users in the European Economic Area and the United Kingdom, our legal bases depend on the information and purpose:
- Health and wellness entries: explicit consent and/or providing the self-tracking features you request. Health data may be special category data and is handled with additional safeguards.
- Premium subscription status: performance of a contract and purchase support.
- Support messages and feedback: legitimate interests in responding to requests and improving PainFlow.
- Website language preference cookie and basic security logs: legitimate interests in providing a functional, secure website.
- Legal, safety, and compliance uses: legal obligations and legitimate interests.
5. Health data protections
Health and wellness information is sensitive. We do not sell your health data. We do not use health data for third-party advertising, behavioral advertising, or cross-app tracking. We do not share health data with advertisers or data brokers.
PainFlow does not integrate with Apple Health, HealthKit, or other external health services. Health and wellness entries are based on information you choose to enter in the app.
6. Premium subscriptions
PainFlow offers optional Premium features through monthly and yearly subscriptions purchased in the app using Apple In-App Purchase. Apple processes payments and manages billing, renewals, cancellations, refunds, and payment method information.
PainFlow may receive limited subscription status information from Apple so the app can unlock Premium features, verify active access, and provide purchase support.
7. When information may be shared
We may share limited information with service providers that help us operate PainFlow, such as hosting, analytics, crash reporting, purchase validation, and customer support providers. These providers may process information only for the services they provide to us and must protect it appropriately.
We may also disclose information if required by law, to protect rights and safety, or with your explicit consent.
8. Data retention
We keep personal information only as long as needed to provide PainFlow, comply with legal obligations, resolve disputes, maintain security, and enforce our agreements. You may request deletion of personal data associated with your support requests or other information we control by contacting hello@painflow.app.
9. Your choices and rights
You may be able to access, update, export, or delete information through the app. You may also contact us to request access, correction, deletion, or restriction of personal information, subject to applicable law.
If you are in the European Economic Area or the United Kingdom, you may also have rights to object to certain processing, request data portability, withdraw consent where processing is based on consent, and lodge a complaint with your local data protection authority or the UK Information Commissioner's Office.
You can manage App Store subscriptions, cancellation, renewal, and refund options through your Apple Account. You can control app permissions, such as notifications, in iOS Settings. Disabling some permissions may limit certain features.
10. Children
PainFlow is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we will take appropriate steps to delete it.
11. Security
We use reasonable administrative, technical, and organizational measures to protect personal information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
12. International use
PainFlow may be operated and supported from different countries. Where personal information is transferred internationally, we take steps designed to protect it according to applicable law.
13. Changes to this policy
We may update this Privacy Policy as PainFlow changes. When we do, we will update the date above. Material changes may also be communicated in the app or by other appropriate means.
