For privacy questions or to exercise your rights, email support@zenfityoga.com with "Privacy Request" in the subject line.
We do not collect precise location, contacts, photos, microphone or camera data, or biometric data.
When you tap "Get Started", the App creates an anonymous account so your progress can be saved. Usage analytics, error reports and the profile and progress you enter are linked to that anonymous identifier. You can connect an email, Apple or Google account later and keep all your progress. If you delete the App without connecting an account, your progress may not be recoverable.
| Processing | Legal basis | GDPR article |
|---|---|---|
| Providing the App, your account, sessions and progress | Performance of a contract | Art. 6(1)(b) |
| Subscriptions and payments | Performance of a contract | Art. 6(1)(b) |
| Personalizing recommendations from your profile | Performance of a contract | Art. 6(1)(b) |
| Analytics and improving the App (PostHog) | Legitimate interest | Art. 6(1)(f) |

Where we rely on legitimate interest, we have weighed it against your rights. You can object at any time (see section 11).
To find bugs and understand where the App is confusing, PostHog and Sentry can record session replays: a reconstruction of the screens you see and the taps you make.
Replays are used only to improve the App. To have your replays deleted, email support@zenfityoga.com.
We do not sell or rent your personal data, and we do not share it for cross-context behavioral advertising. We use these service providers, under data processing agreements:
| Provider | Purpose | Data | Location |
|---|---|---|---|

| Sentry | Error tracking and session replay | Crash reports, replays, user ID, email | US |
| RevenueCat | Subscription management | Purchase history, subscription status, device identifiers, tracking choice | US |
| Apple / Google | Sign-in, app stores, payments | Account identifiers, purchase records | US |
| Cloudflare | Delivering session videos | IP address and request logs (no account data) | Global |
| Vercel | Hosting the Website | IP address and request logs | Global |
We may also disclose information to comply with the law, to protect rights and safety, or in a merger or acquisition (you will be notified).
We are based in the EU (Spain). Some providers process data in the United States. These transfers rely on the EU-U.S. Data Privacy Framework where the provider is certified, or the European Commission's Standard Contractual Clauses. You can ask us for a copy of the safeguards at support@zenfityoga.com.
| Data | Kept for |
|---|---|

| Session replays (PostHog) | 30 days |
| Error reports and replays (Sentry) | 90 days |
| Purchase records | As required by tax and accounting law |
Anonymous accounts that are inactive for 24 months may be deleted.
You have the right to access, correct, delete, restrict and port your data, to object to processing based on legitimate interest (including analytics and session replays), and to withdraw consent at any time (for example by turning off Apple Health access in iOS Settings). You can also complain to the Spanish Data Protection Agency (AEPD) (www.aepd.es) or your local authority.
Email support@zenfityoga.com to exercise your rights. We answer within 30 days and may need to verify your identity.
California residents can ask to know, delete and correct their personal information, and will not be discriminated against for doing so. We do not sell or share personal information. Categories we collect: identifiers (name, email, account and device IDs), internet activity (usage data, session replays), commercial information (subscriptions) and characteristics you provide (birthday, gender). Email support@zenfityoga.com or use zenfityoga.com/delete-account. We answer within 45 days.
We encrypt data in transit and at rest, restrict access so each user can only read their own data (row-level security), and require data processing agreements from our providers. No system is perfectly secure, but we work to protect your data and will notify the authority within 72 hours, and you without undue delay, if a breach puts your rights at high risk.
ZenFit is made for adults. We do not knowingly collect data from children under 16. If you believe a child has given us personal data, contact support@zenfityoga.com and we will delete it.
zenfityoga.com uses PostHog analytics in cookieless mode: we measure page views and button clicks without setting cookies or storing identifiers on your device. When you open a download link, we record the campaign and source (for example "TikTok") to learn which posts bring people to the App. The Website does not use advertising cookies.
We may update this policy. We will change the date at the top, and for important changes we will tell you in the App. Where consent is needed, we will ask again.
