Privacy Policy
Effective date: June 9, 2026 · Last updated: June 9, 2026
This Privacy Policy describes how PCOS Bae: PCOS Nutrition & Cycle ("PCOS Bae," "we," "us," or "our") collects, uses, and protects your information. This policy applies to the PCOS Bae mobile application (the "App").

Who We Are
Data Controller: Anton, individual developer
Location: Batumi, Georgia
Contact: support@byanton.dev
Website: byanton.dev
As a small-scale individual developer, we are not required to appoint a Data Protection Officer under GDPR Article 37. For all privacy inquiries, contact us at the email above.
Summary: PCOS Bae is a gentle wellness companion for women with PCOS — it helps you scan meals, track your cycle, symptoms, mood and weight, learn, and prepare for doctor visits. Your meals, body metrics, cycle, symptom and mood data are stored only on your device. When you scan a meal, the food photo you take or choose (or a text description you type) is sent to Google Gemini (via our Cloudflare Workers proxy) to estimate calories, macros and PCOS-friendliness scores — processed in real time and not stored on our servers, never sold, and never used to train AI models. We require no account, collect no name, email, location, contacts, or tracking identifiers, show no ads, and do not read Apple Health. PCOS Bae is a wellness tool and is not medical, nutritional, or healthcare advice.
1. AI System Disclosure (EU AI Act Article 50)
You are interacting with an artificial intelligence system. Specifically:
- Meal analysis (estimated food name, portion, calories, protein/carbs/fat, fiber, added sugar, and the PCOS-friendliness scores — blood-sugar / insulin, inflammation and hormone support — with a short reason and a gentle swap suggestion) is produced by Google Gemini 2.5 Flash, an AI model from Google LLC, accessed via Google Vertex AI.
- AI estimates are approximate and may contain inaccuracies. They are a wellness aid only — not medical or nutritional advice, not a clinical measurement, and not a diagnosis or treatment of PCOS or any condition. You can edit any value before saving.
- Your daily calorie/macro targets and any cycle, fertility-window or projection estimates are calculated on your device from the figures you enter, using standard formulas (e.g. Mifflin–St Jeor). They are gentle estimates, not prescriptions.
2. Information We Collect
2.1 Information You Provide
| Data | Purpose | Storage | Retention |
|---|
| The food photo you capture or pick, or a typed meal description | Estimating calories, macros and PCOS-friendliness scores for that meal | The chosen image/text is sent ephemerally to Google Gemini for the request; the photo may also be saved with the meal on your device | Cloud: processed in real time, not stored on our servers. Local: until you delete the meal or the App |
| Meal log (name, portion, calories, protein/carbs/fat, fiber, added sugar, PCOS scores) | Showing your day, history and trends | On your device only (SwiftData) | Until you delete it or the App |
| Body metrics (age, height, weight, desired weight, goal, activity level) | Calculating your nutrition targets and progress | On your device only (SwiftData) | Until you change it or delete the App |
| Cycle data (last period date, cycle length, period length, logged period starts, regularity) | Showing the cycle calendar and gentle, irregular-aware phase guidance | On your device only (SwiftData) | Until you change it or delete the App |
| PCOS symptoms, mood check-ins, and notes you log | Tracking how you feel over time and preparing a doctor-visit report | On your device only (SwiftData) | Until you delete it or the App |
| Preferences (units, theme, reminders on/off) | Personalising the experience | On your device (UserDefaults / SwiftData) | Until you change it or delete the App |
2.2 Information Collected Automatically
- Anonymous subscription status — managed by Apple StoreKit (and RevenueCat for entitlement verification) to confirm PCOS Bae Pro access. No name or email is associated with it.
- Anonymous usage signals — via TelemetryDeck (privacy-first analytics, EU-hosted) to understand which features are used and improve the app. No personal data, no advertising identifiers, no cross-app tracking, and no meal photos or health data are ever sent.
- IP address — visible to our Cloudflare Workers proxy only for rate-limit keying (abuse / cost protection). The IP is never stored in our cache, never shared with Google, and never sold.
- Locale and app version — sent as standard request headers (for response language and diagnostics). Visible to Cloudflare in request logs (~24 h retention).
2.3 Information We Do NOT Collect
- Email address, phone number, name, or physical address (unless you choose to email our support)
- Location (GPS) — we never request location permission
- Contacts, calendar, or microphone
- Apple Health / HealthKit — PCOS Bae does not read from or write to Apple Health
- Advertising identifiers (IDFA) — we do not use App Tracking Transparency
- Browsing history, cookies, or web tracking pixels
- We do not create user accounts or require registration; no Apple, Google, or social sign-in
Camera & Photos: PCOS Bae requests camera access (to photograph a meal) and uses the system photo picker (to choose an existing photo). Only the single image you take or select for a scan is used — the App never browses, scans, or uploads your photo library, and you can decline camera access and type a description instead.
3. Legal Basis for Processing (GDPR Article 6)
Health-related data (such as PCOS symptoms, cycle and weight) is a special category under GDPR Article 9. We process it on your device solely to provide the features you request; where any processing requires it, our basis is your explicit consent (Article 9(2)(a)), which you can withdraw at any time by deleting the data or the App.
| Processing Activity | Legal Basis |
|---|
| Sending your meal photo / text to the cloud AI | Performance of a contract / your request — only happens when you tap "scan" or "analyze" |
| Storing your meals, body metrics, cycle, symptom and mood data locally | Performance of a contract + your explicit consent (Article 9(2)(a)) for health data |
| Subscription processing | Performance of a contract (via Apple StoreKit and RevenueCat) |
| Rate limiting and abuse prevention | Legitimate interest (service availability, AI-cost protection, and security) |
4. Third-Party Services
Apple Guideline 5.1.2(i) Disclosure: The following named third parties may process your data. Your meal photo or text is shared with Google's AI service only when you actively scan or describe a meal.
| Provider | Service | Data Sent | Retention by Provider |
|---|
| Google LLC (Vertex AI — Gemini 2.5 Flash) | Estimating calories, macros and PCOS-friendliness scores from your meal | The single meal image or text description you submit + locale | Not retained. Not used for model training per Vertex AI / Gemini enterprise data-usage terms. |
| Cloudflare, Inc. (Workers) | Secure proxy routing between the App and Google's AI API; per-IP rate limiting | Encrypted request body (HMAC-SHA256 signed); IP visible to the rate limiter only | Rate-limit counters: short sliding window. Request logs ~24 h. No long-term storage of your data. |
| Apple Inc. (StoreKit) | In-app purchase / subscription processing | Managed by Apple per Apple's Privacy Policy | Managed by Apple |
| RevenueCat, Inc. | Subscription receipt validation and entitlement verification | Anonymous subscription status and country code | Retained per RevenueCat's privacy policy for the subscription lifetime + audit period |
| TelemetryDeck (Telemetry Deck GmbH, EU) | Privacy-first anonymous usage analytics | Anonymous event signals only (e.g. "paywall viewed", "scan succeeded") — no personal data, no device IDs, no cross-app tracking | Per TelemetryDeck terms, GDPR-compliant, EU-hosted |
All cloud data transfers use TLS encryption, HMAC-SHA256 request signing, and a short timestamp anti-replay window. The meal photo or text you submit is transmitted only for the duration of a single request and is not written to disk on the Cloudflare proxy.
5. Data Storage and Retention
| Data | Where Stored | Retention Period |
|---|
| Meals, photos, body metrics, cycle, symptom, mood data, history, preferences | Your device (SwiftData, app sandbox) | Until you delete it in-app or uninstall the App |
| Meal image / text in transit to the AI provider | Cloudflare Workers (in memory) → Google Cloud (in memory) | Processed in real time, not written to disk by our proxy |
| Rate-limit counters | Cloudflare Workers | Short sliding window, per IP |
| Subscription data | Apple servers, RevenueCat servers | Managed per their respective privacy policies |
Because your data lives on your device, deleting the App permanently removes all of it — meals, photos, body metrics, cycle, symptom and mood history. There is no server-side copy to request or erase, and your data does not sync between devices.
6. Children's Privacy
PCOS Bae is a reproductive- and metabolic-wellness tool intended for adults (18+) managing their own health. It is not directed to children.
- COPPA: We do not knowingly collect personal information from children under 13. If we discover such data was collected, we will delete it immediately.
- GDPR Article 8: The cloud AI features are not intended for minors below your country's digital age of consent.
- We do not sell, share, or use anyone's data for advertising or AI model training.
7. Your Rights
All Users
- Access: Your full history is visible inside the App (Eat, Track, and the doctor report).
- Deletion: Delete any entry in-app, use "Delete all data" in Settings, or remove all data by deleting the App. Because the data is on-device, this is immediate and complete.

9. International Data Transfers
Meal images/text sent to AI features are processed in the United States (Google Cloud Platform, Cloudflare). These transfers are protected by EU Standard Contractual Clauses (GDPR Article 46), the Google Cloud Data Processing Addendum, Cloudflare's data processing agreement, the EU-US Data Privacy Framework where applicable, and TLS encryption with HMAC-SHA256 request signing.
10. Data Security
- All data in transit encrypted using TLS (HTTPS)
- All API requests to our Cloudflare Workers proxy are signed with HMAC-SHA256 and a short timestamp window to prevent tampering and replay attacks, plus a bundle-identifier check and per-IP rate limiting
- Your meals, body metrics, cycle, symptom and mood data are stored on your device, protected by iOS sandboxing
- Server-side processing keeps your image/text in memory only — not written to disk on the proxy
- No user accounts, no passwords, no saved credentials — minimal attack surface
11. No Tracking, No Advertising
- PCOS Bae does not track you across apps or websites
- We do not use advertising identifiers (IDFA) or App Tracking Transparency
- We do not display advertisements
- We do not share data with data brokers or ad networks
- We do not sell or share your personal information under any circumstances
12. Data Breach Notification
In the unlikely event of a data breach affecting your personal information, we will notify affected users and relevant supervisory authorities within 72 hours of discovery as required (GDPR, LGPD, KVKK), and take immediate steps to contain and remediate it.
13. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be communicated through an updated "Last updated" date and, where practicable, an in-app notice. Continued use after changes constitutes acceptance.
14. Not Medical Advice
PCOS Bae provides general wellness and informational estimates only. Calorie and macro targets, cycle-phase guidance, projections, PCOS-friendliness scores, symptom and mood tracking, and the doctor-report PDF are not medical, nutritional, diagnostic, or healthcare advice, and are not a substitute for a physician, endocrinologist, registered dietitian, or other qualified professional. PCOS is a medical condition that should be diagnosed and managed with a healthcare provider. Cycle information is an estimate and is not a contraceptive or fertility method — this is especially important with PCOS, where cycles are often irregular. Do not use PCOS Bae to diagnose or treat any condition. If you are pregnant or breastfeeding, have a medical condition, or have a history of disordered eating, please consult a healthcare professional before changing your diet, and seek help from a qualified provider or a local support line if you need it.
