Privacy Policy
Last updated: 24 August 2026
nu3 ("the app") is operated by Beyer Ventures S.L., Valencia, Spain. This policy describes what data the app processes and what happens to it. The short version: your food log lives on your phone, we do not know who you are, and photos are processed transiently for analysis and are not stored by us.
What stays on your device
- Your meal history, including saved photos.
- Your settings and nutrition targets.
- Your hints and edits to AI estimates.
This data is stored only in the app's local storage. We have no accounts, no login, and no server-side copy of your food log. If you delete the app, this data is deleted with it. You can export your data as a file from Settings at any time.
What is processed when you scan a meal
When you tap Analyze, the photo and any text hint you typed are uploaded over an encrypted connection to our backend and forwarded to Anthropic, our AI provider, to produce the nutrition estimate. This processing is transient: our backend does not store the photo or the hint. The upload is subject to Anthropic's data handling terms. Location metadata (EXIF/GPS) is stripped from the photo on your device before anything is uploaded.
What we store on our servers
- A random device identifier generated by the app on first launch. It contains no personal information and is not linked to your identity.
- The number of AI scans that identifier has used (to enforce the free allowance).
- Whether that identifier has an active subscription.
That is the complete list. We store no names, no email addresses, no photos, and no meal data.
Subscriptions
Purchases are handled by Apple's App Store or Google Play. We never see your payment details. We use RevenueCat to validate subscription receipts; RevenueCat receives the anonymous device identifier and purchase receipt data, not your identity.
Where processing happens
Our backend and AI provider process scan requests on servers in the United States. For users in the EU/EEA, transfers rely on the providers' applicable safeguards (standard contractual clauses or an adequacy framework). Because scans are transient and pseudonymous, no profile of you is built or retained.
Legal basis (EU/EEA users)
Processing a scan you request is performance of a contract (Art. 6(1)(b) GDPR). Metering the free allowance and preventing abuse is our legitimate interest (Art. 6(1)(f) GDPR).
Your rights
Because your food log is stored only on your device, you exercise access, export, and deletion directly in the app (Settings → Export / Clear all data; or delete the app). For the server-side scan counter, contact us with your device identifier (shown in Settings) and we will delete the record. EU/EEA users additionally have the right to lodge a complaint with a supervisory authority.
Children
The app is not directed at children under 16.
Changes
We will update this page when the policy changes and note the date above. Material changes will be announced in the app.
Jurisdiction
This policy is governed by the laws of Spain, without limiting any mandatory rights or remedies available to you under applicable data protection or consumer law.
