- Personal identity information (name, email address, phone number)
- Precise or coarse location data
- Contacts, photos, or other device data
- Financial information (payments are processed by Apple)
- Advertising identifiers (IDFA) — Wattora contains no advertising SDKs
4. Legal Basis for Processing (GDPR)
We process data under the following legal bases as defined by the General Data Protection Regulation (EU 2016/679):
- Contract performance (Art. 6(1)(b)) — delivering the service you requested, including displaying prices for your selected country and managing your subscription.
- Legitimate interest (Art. 6(1)(f)) — anonymous usage analytics and crash reporting to keep the app stable and improve it.
- Consent (Art. 6(1)(a)) — push notifications for price alerts (you can disable them at any time in the app or in device settings).
5. Third-Party Services
Wattora integrates the following third-party services:
- TelemetryDeck — anonymous usage analytics. The device identifier is hashed on your device before sending and is not linked to your identity. See TelemetryDeck’s Privacy Policy.
- Sentry — crash reporting and diagnostics, processed in Sentry’s EU (Germany) region and not linked to your identity. See Sentry’s Privacy Policy.
- RevenueCat — subscription management using a random anonymous app user ID (no name, email or Apple ID). We never receive or store your payment details. See RevenueCat’s Privacy Policy.
- Apple (App Store / StoreKit) — processes all subscription payments. Apple handles payment information directly; we never receive your payment details. See Apple's Privacy Policy.
- ENTSO-E Transparency Platform — public wholesale electricity market data source. No user data is shared with ENTSO-E.
- Cloudflare — hosts our backend (Cloudflare Workers and D1 database), which serves price data and stores push-alert registrations. See Cloudflare's Privacy Policy.
6. Data Retention
- Device push tokens and their alert settings are kept while alerts are registered. Tokens that Apple reports as invalid (for example after the app is deleted) are removed automatically. To have your registration deleted at any time, contact us.
- Country/zone preferences are stored on your device; they are stored on our server only together with a push token if you enable price alerts.
- Subscription status is retained while your subscription is active and for a reasonable period afterward for record-keeping.
- Anonymous analytics data is aggregated and cannot be linked back to individual users.
7. Data Storage and Security
Our backend runs on Cloudflare Workers. Data is transmitted over encrypted connections (HTTPS/TLS). We implement appropriate technical and organizational measures to protect the data we process.
8. International Data Transfers
Our service providers (Cloudflare, TelemetryDeck, Sentry, RevenueCat and Apple) may process data outside the European Economic Area under their data processing terms, including Standard Contractual Clauses approved by the European Commission where applicable.
9. Your Rights Under GDPR
If you are in the European Economic Area, you have the following rights:
- Access — request a copy of data we hold about you.
- Rectification — correct inaccurate data.
- Erasure — request deletion of your data.
- Restriction — limit how we process your data.
- Portability — receive your data in a structured, machine-readable format.
- Objection — object to processing based on legitimate interest.
- Withdraw consent — at any time, without affecting the lawfulness of prior processing.
To exercise any of these rights, contact us at [email protected]. We will respond within 30 days.
You also have the right to lodge a complaint with your local Data Protection Authority (DPA). For Italy, this is the Garante per la protezione dei dati personali.
10. Children's Privacy
Wattora is not directed at children under the age of 16. We do not knowingly collect data from children. If you believe a child has provided us with data, please contact us and we will delete it promptly.
11. Changes to This Policy
We may update this privacy policy from time to time. If we make material changes, we will notify you through the app or by other appropriate means. The "effective date" at the top of this page indicates when the policy was last revised.
