1Introduction and controller identification
Your privacy is a priority for us. This Privacy Policy describes, transparently and in detail, which personal data the Monju app collects, why it collects it, how it is used, who it is shared with, how long it is retained and which rights you have over that data, in compliance with Brazilian Law No. 13,709/2018 — the General Data Protection Law (LGPD).
Monju is a mobile app (iOS and Android) for health and wellbeing tracking, aimed at people undergoing treatment with GLP-1 class medications (such as Mounjaro/Tirzepatide, Ozempic, Wegovy, Saxenda, Victoza, Trulicity and Rybelsus). This Policy applies to every feature of the app, to the healthcare professional web portal and to any other service we provide.

4.9. Feedback sent by the user
Feedback messages, ratings given in in-app prompts and e-mail communication with support.
5How data is collected
Data is collected in three ways: (5.1) provided directly by you through onboarding, tracking screens and settings; (5.2) collected automatically (usage, device, diagnostics, analytics) by native SDKs; and (5.3) received from third parties — Google Sign-In (name, e-mail, public picture), Sign in with Apple (name and real or relay e-mail) and RevenueCat (identifiers and subscription status).
6Specific purposes of processing
Data is processed in order to: (6.1) provide the tracking service (records, BMI calculations, goals, estimated medication level, charts); (6.2) power AI features (macro estimates, reading of lab and bioimpedance reports, health assistant, recipe images); (6.3) send reminders and treatment-related communications (push, WhatsApp, check-in, operational notices); (6.4) share data with healthcare professionals; (6.5) manage your account and subscription; (6.6) continuously improve the product (aggregated, anonymized analytics); (6.7) ensure security and prevent fraud; (6.8) comply with legal obligations; and (6.9) send marketing communications (optional and revocable).
7Legal bases for processing
For each purpose we apply one or more legal bases from the LGPD: performance of a contract (Art. 7, V) for service provision and account management; specific explicit consent (Art. 11, I) for sensitive health data, AI features and sharing with a professional; consent (Art. 7, I) for push/WhatsApp reminders and marketing; legitimate interest (Art. 7, IX) for product improvement, analytics and security, over aggregated/anonymized data; and compliance with a legal obligation (Art. 7, II) where required. Consent for sensitive data is collected specifically and prominently during onboarding and may be withdrawn at any time.
8Data sharing with third parties
Monju shares data only when strictly necessary to provide the services. The main processors are:
- Google LLC — AI (Gemini API): processes meal descriptions and photos, lab and bioimpedance reports, assistant messages and a summary of your health context — without your name, e-mail, phone number or any data that directly identifies you. Requests go through a secure proxy (Supabase Edge Function) over HTTPS/TLS, only after your explicit consent. The data is not used to train Google models and is retained only for as long as needed to generate the response.
- Supabase, Inc. — database, authentication and storage: stores your data with encryption at rest (AES-256) and in transit (TLS), per-user Row Level Security and encrypted backups. SOC 2 Type II certified.
- RevenueCat, Inc. — subscriptions: receives an anonymous identifier, store receipts and subscription status. It does not receive your name, e-mail, health data or financial data.
- Google (Sign-In and Play Store) and Apple (Sign in with Apple and App Store): authentication and payment processing in the respective stores. No health data or password is shared.
- Resend, Inc. — transactional e-mails: sends e-mails to the professional you nominate (first name and secure link only) and operational e-mails to you.
- 360dialog GmbH — WhatsApp Business API: sends generic dose reminders (no sensitive details), only if you provide your number.
- Microsoft — Clarity (analytics): anonymous usage behavior with a non-reversible hashed identifier; no health data, name or e-mail.
- Google — YouTube Data API: recipe search terms only; no personal data is sent.
- Infrastructure providers (Vercel, AWS, Cloudflare): serve the professional web portal and process operational logs for short periods.
We do not sell your data; we do not share health data with insurers, health plans, employers or advertisers; we do not use your data for third-party targeted advertising; and we do not send your photos, lab reports or health content to any third party other than those described above.
9International data transfers
Some processors are located outside Brazil — mainly in the United States (Google, Supabase, RevenueCat, Apple, Resend, Microsoft), in Singapore (Supabase) and in Germany (360dialog). Transfers are carried out under Chapter V of the LGPD (Arts. 33 to 36), based on consent, performance of a contract, compliance with a legal obligation and specific contractual clauses. These providers adopt security standards equivalent to or higher than those required by the LGPD (SOC 2, ISO 27001, GDPR compliance where applicable).
10Storage and security
We adopt technical and organizational measures to protect your data. Technical measures: encryption in transit (HTTPS/TLS 1.2+) and at rest (AES-256); secure local token storage (Keychain/Keystore); Row Level Security in the database; private storage buckets with signed URLs; API keys kept exclusively server-side; token-based validation in the professional portal. Organizational measures: access restricted to authorized people, access logs for sensitive data, team training, an incident response plan and periodic review. In the event of a relevant incident, we will notify the ANPD and the data subjects as set out in Art. 48 of the LGPD.
11Data retention and account deletion
Your data is retained while your account is active, for as long as it is necessary for the contracted services, or while there is a legal obligation or legitimate interest in defending rights.
How to delete your account: inside the app, under Profile → Delete account (deletion permanently erases your data and files through a dedicated server-side function); or by e-mail to contato@meuguru.com with the subject "Account deletion request — LGPD", answered within 15 business days.
After deletion, database records and files are erased immediately; encrypted backups may persist for up to 30 days; operational logs for up to 90 days. Financial transaction data is retained by the app stores for statutory tax periods (5 years), and anonymized aggregated usage data may be kept.
12Data subject rights (LGPD Art. 18)
You have the following rights, which you may exercise free of charge: confirmation that processing exists; access to your data; correction; anonymization, blocking or deletion of unnecessary data or data processed in breach of the law; portability; deletion of data processed on the basis of consent; information about sharing; information about the possibility of refusing consent; withdrawal of consent; and objection to processing.
How to exercise them: send an e-mail to contato@meuguru.com stating your name, the e-mail linked to your account and the right you wish to exercise. We will respond within 15 business days. In the event of the data subject's death, heirs or legal representatives may exercise these rights upon presentation of documentation.
13Cookies, tokens and similar technologies
The app does not use traditional HTTP cookies, but it does use analogous technologies in the mobile environment: authentication JWT tokens stored securely (Keychain/Keystore); installation identifiers for operational purposes and anonymized analytics; local state persistence on the device (AsyncStorage/MMKV). The professional web portal may use strictly necessary cookies to keep the session active, without tracking or advertising.
14Push notifications, e-mail and WhatsApp
With your authorization, we may send: push notifications (dose reminders, daily check-in and operational notices); operational e-mails (account confirmation, recovery, security and billing alerts, legal notices); marketing e-mails (optional, with unsubscribe available at any time); and WhatsApp messages (dose reminders, only if you provide your number and enable them). You can turn off any of these channels at any time.
15Children and adolescents
Monju is not directed at anyone under 16, and we do not knowingly collect data from children under 13. Adolescents aged 16-17 may use the app with informed consent; those aged 13-15 only with the consent of a legal guardian (Art. 14 of the LGPD); children under 13 must not use the app. In the app stores, the rating is 17+ (App Store) and adult (Play Store). Parents or guardians may contact us at contato@meuguru.com.
16Artificial intelligence — clarifications
Monju uses models from the Gemini family (Google), version 2.5, accessed through the Google AI API. Every call goes through a server-side proxy (Supabase Edge Function) that does not include identifiable personal data in the payload — only the content required (the text of your question, the photo of the meal or of the lab report). The API key stays exclusively on the server. Under the Google AI terms, data sent through the API is not used to train models and is processed only for as long as needed to generate the response.
AI responses (macro estimates, interpretation of lab results, assistant) are estimates that may contain errors and do not constitute a diagnosis, a prescription or a medical recommendation. Monju does not make automated decisions with legal effects (Art. 20 of the LGPD); the AI features are informational and educational.
17Important medical notice
Monju is not a medical device, does not diagnose, does not prescribe medication and does not replace guidance from a qualified healthcare professional. All information is informational and educational in nature. Before starting, stopping, changing the dose of or replacing any medication, always consult a doctor. In case of a severe symptom, a serious adverse reaction or an emergency, seek immediate medical care or call your local emergency number (in Brazil, SAMU — 192).
18Changes to this Policy
We may change this Policy at any time. Significant changes will be communicated through a prominent notice in the app, an e-mail to your registered address and an update to the "version" date at the top of this document. Continuing to use the app after publication constitutes tacit acceptance. Previous versions are available on request at contato@meuguru.com.
