Privacy Policy
This Privacy Policy explains how Weighra collects, uses, stores, and shares personal data when you use the service, create an account, purchase PRO access, or interact with analytics and AI-related features.
Effective date: May 5, 2026
1. Data Controller
The controller of your personal data for Weighra is Tomasz Pilarczyk, Żwirki i Wigury 16, 66-620 Gubin, Poland, Tax ID PL9261689360.
If you have privacy questions or want to exercise your rights, contact support@weighra.com.
2. Personal Data We Collect
Depending on how you use Weighra, we may collect account data such as your email address, authentication provider, and account identifiers.
We may collect profile and tracking data such as age, sex, height, goal weight, goal direction, weigh-in day, unit system, baseline activity level, calorie entries, optional macronutrient entries, weekly activity level, weigh-ins, weekly results, milestone images, and related in-app content.
We may collect subscription and transaction-related information such as plan type, subscription status, renewal or cancellation state, billing metadata, and Stripe-related payment events. We do not store full card details ourselves.
We may collect communications and support data if you contact us.
We may collect technical and usage data, including device, browser, approximate interaction data, and analytics information through Google Analytics.
3. How We Use Personal Data
We use personal data to create and manage accounts, authenticate users, operate the tracker, display weekly insights, store weigh-ins and calorie records, support milestone image features, provide subscriptions, prevent abuse, analyze service usage, and communicate with users about service-related matters.
Where AI-related features are used, we also process the relevant text, image, and context inputs necessary to generate the requested estimate or insight output.
4. Legal Bases for Processing
Where the General Data Protection Regulation applies, we typically process personal data on one or more of the following bases: performance of a contract with you, compliance with legal obligations, legitimate interests in operating, securing, improving, and analyzing the service, and consent where consent is required.
If we rely on consent for a specific activity, you may withdraw that consent at any time without affecting prior lawful processing.
5. Authentication and Password Security
If you sign in with Google, authentication data is processed through Google OAuth.
If you use an email and password account, passwords are hashed using bcrypt and are not stored in plaintext.
6. Payments
Payments and recurring subscription billing are processed by Stripe. Stripe may receive and process personal and transaction data necessary to complete payments, manage subscriptions, prevent fraud, and comply with legal obligations.
We receive billing and subscription status information needed to activate, maintain, cancel, or expire access to PRO features.
7. Analytics and Cookies
We use Google Analytics to understand how visitors and users interact with Weighra, such as which pages are visited and how features are used.
Weighra may also use cookies, local storage, and similar technologies to maintain sessions, remember preferences, keep the app functioning, and support analytics.
Your browser or device may offer controls for cookies and similar technologies. Blocking some technologies may affect how the service works.
8. Sharing of Personal Data
We do not sell your personal data.
We may share personal data with trusted service providers that help us operate Weighra, including Google OAuth, Stripe, and Google Analytics, and with other providers that host, secure, or support the service where necessary.
We may also disclose data where required by law, regulation, legal process, or to protect rights, safety, or the integrity of the service.
9. International Data Transfers
Some service providers we use may process data outside your country, including outside the European Economic Area. Where required, we take steps intended to ensure appropriate safeguards are in place for such transfers.
10. Data Retention
We retain personal data for as long as reasonably necessary to provide the service, maintain your account, meet legal obligations, resolve disputes, enforce agreements, and protect the service.
Account, subscription, and tracking data may be retained until account deletion or closure, subject to legal, accounting, fraud-prevention, or security retention requirements.
11. Data Security
We use reasonable technical and organizational measures intended to protect personal data against unauthorized access, loss, misuse, or disclosure.
No online service is completely secure, and we cannot guarantee absolute security.
12. Your Rights
Depending on your location and applicable law, you may have the right to request access to your personal data, rectification, deletion, restriction of processing, objection to certain processing, portability, and withdrawal of consent where consent is the legal basis.
You may also have the right to lodge a complaint with a competent supervisory authority, including in the European Union or your country of residence where applicable.
To exercise rights related to your data, contact support@weighra.com.
13. Children
Weighra is not intended for use by young children. If you believe a child has provided personal data in violation of applicable law, contact us and we will review the request.
14. Third-Party Sites and Services
Weighra may connect to or rely on third-party services. Their privacy practices are governed by their own policies, and we encourage you to review them when you use those services.

We may update this Privacy Policy from time to time. The version published on this page is the current version. If material changes are made, we may provide additional notice within the service where appropriate.
