Privacy policy.

WHO WE ARE Equil AI ("Equil", "we", "us", or "our") is operated by a solo developer, based in Bulgaria (European Union). You can contact us at [email protected]. This policy explains what data the Equil AI app collects, how we use it, who we share it with, and the choices and rights you have.

Because we are based in the EU and host data in the EU, this policy is written to align with the EU General Data Protection Regulation (GDPR). Where you live, additional or different rights may apply.

01SUMMARY (THE SHORT VERSION)

• Equil is a personal nutrition and fitness coaching app. To do its job, it processes health, fitness, nutrition, and (optionally) location data that you provide or grant access to.
• We use this data only to provide and improve the app's features for you.
• We do not sell your personal data, and we do not use your health data for advertising.
• Apple Health (HealthKit) data is used on your device and to power your coaching; it is never used for advertising or sold, consistent with Apple's requirements.
• You can request deletion of your account and associated data at any time from within the app.

02DATA WE COLLECT

2.1 · Account information

• Email address and name, and your sign-in method (Sign in with Apple, Google, or email/password).
• If you use Sign in with Apple, Apple may provide a private relay email instead of your real address.

2.2 · Health & fitness data (Apple Health / HealthKit)

With your explicit permission, Equil reads the following from Apple Health to power your coaching features:

• Workouts; active and resting energy burned; heart rate; heart rate variability (HRV); resting heart rate; steps; walking/running distance; respiratory rate; VO₂ max; body mass.
• Sleep analysis.
• Menstrual flow (used only for cycle-aware features, and only if you choose to enable it).

With your permission, Equil writes the following back to Apple Health:

• Workouts and workout routes; dietary energy, protein, carbohydrates, fat, and water; body mass.

Apple Health data is accessed on your device. We do not use Health data for advertising or marketing, we do not sell it, and we do not share it with third parties for their own purposes, in accordance with Apple's HealthKit terms.

2.3 · Location data

• If you record an outdoor activity (walk, hike, run, cycle), Equil uses your device's GPS to map your route and distance.
• Your approximate location may also be used to provide local weather (via Apple WeatherKit) for the sweat/hydration forecast feature.
• Location is used only for these features. We do not use location for advertising or for tracking you across apps or websites.

2.4 · Information you enter

• Meals and food logs, including photos of food you choose to scan.
• Training programs you create or import, including PDFs, photos, or screenshots of existing plans.
• Body weight, supplements, menstrual-cycle entries, and your goals and preferences.

2.5 · Subscription & purchase data

• Subscription status and transaction identifiers are processed through Apple's App Store and our subscription manager, RevenueCat. We do not receive or store your full payment card details.

2.6 · Technical & diagnostic data

• Basic technical information needed to operate and improve the service — such as app version, device type and operating-system version, and anonymous error and crash logs used for diagnostics, stability, and research into how features perform. This data is used to fix bugs and improve the app, not to identify you personally or to advertise to you.

03HOW WE USE YOUR DATA

• To create and secure your account and authenticate you.
• To calculate your nutrition targets, recovery scores, training recommendations, and other coaching features.
• To analyze food photos and barcodes you submit, so we can estimate nutrition.
• To map your activity routes and provide weather-based hydration guidance.
• To manage your subscription and free trial.
• To maintain, troubleshoot, and improve the app.
• To comply with legal obligations.

Under the GDPR, our legal bases for processing are: performing our contract with you (to provide the app), your consent (e.g. for Health and Location access, which you can withdraw at any time), and our legitimate interests in operating and improving the service.

04AI PROCESSING OF FOOD PHOTOS & IMPORTED PLANS

When you scan a meal, the food image is sent to Google's Gemini AI service to estimate its nutritional content. When you import a training plan as a PDF, photo, or screenshot, its contents may likewise be processed by AI to extract the structured program.

This processing is performed by Google as a service provider, through the paid Gemini API, subject to Google's Gemini API terms and its Data Processing Addendum. Under those terms, when the paid Gemini API is used, Google does not use the submitted content or the responses to train or improve its own products. Google logs the submitted content and responses only for a limited period of time, solely to detect and prevent abuse, maintain the safety and security of the service, and meet legal requirements. You can review Google's terms at https://ai.google.dev/gemini-api/terms.

Please avoid including people's faces or other unnecessary personal information in food photos — only the food needs to be captured for nutrition analysis.

05WHO WE SHARE DATA WITH (SERVICE PROVIDERS)

We share data only with the service providers needed to run Equil, and only for that purpose:

• Supabase — Cloud hosting, database, and authentication. Data is hosted in the European Union (Frankfurt, Germany). Involves: account info and the app data you sync.
• Apple — Sign in with Apple, HealthKit, WeatherKit, and App Store payments. Involves: auth identifiers and purchase data; Health and location are processed on-device.

06INTERNATIONAL DATA TRANSFERS

Our primary database is hosted in the European Union. Some service providers (such as Apple and Google) may process data in other countries. Where data is transferred outside the EU/EEA, it is done using appropriate safeguards such as the providers' Standard Contractual Clauses.

09DATA SECURITY

We use reasonable technical and organizational measures to protect your data, including encryption in transit and access controls on our hosted database. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
