1. Controller

Kourion Apps LTD is the controller of personal data processed through Let's buy, except where third-party providers act as separate controllers for their own processing activities.

2. Information we collect

Depending on how you use Let's buy, we may collect and process:

account and identifier data, such as anonymous user IDs generated through Firebase Authentication;
app content you create or sync, such as shopping lists, entries, sharing links, archived data, and related metadata;
subscription and purchase status information provided through Apple and RevenueCat;
device and technical information, such as app version, approximate locale or language, device identifiers used by integrated SDKs, and diagnostic metadata;
usage and event data, such as screen views, taps, app sessions, navigation events, and interactions with paywalls, onboarding, notifications, and list features;
push notification token data, when your device registers for notifications.

3. How we collect information

We collect information in the following ways:

directly from you when you create or edit content in the app;
automatically through SDKs and service providers when you use the app;
from Apple and RevenueCat in connection with subscription purchases and entitlement status.

4. How we use your information

We use information to:

provide core app functionality, including storing, syncing, restoring, and sharing your lists;
authenticate users and maintain app security;
deliver premium subscription features and verify subscription entitlements;
send push notifications when enabled by you;
understand app usage, improve the product, troubleshoot problems, and evaluate new features;
comply with legal obligations and enforce our terms.

5. Third-party services we use

Let's buy uses third-party services that may process personal data on our behalf or for their own service purposes.

Firebase

We use Firebase services, which may include Firebase Authentication, Realtime Database, Cloud Messaging, and related Google infrastructure. Firebase helps us authenticate users, store app data, support syncing and sharing, and deliver notifications.

RevenueCat

We use RevenueCat to manage subscriptions, offerings, and premium entitlement status. RevenueCat may process identifiers, subscription state, purchase metadata, and app user IDs linked to your in-app purchases.

Google Analytics

We may use Google Analytics or related Google analytics tooling to understand app traffic, feature usage, retention, and aggregate behavior trends. Google may collect device, usage, and event data as described in its own documentation and privacy terms.

Amplitude

We use Amplitude for product analytics. Amplitude may collect app events such as sessions, screen views, navigation actions, taps, and selected user properties to help us understand how users interact with Let's buy and to improve the experience.

6. Push notifications

If you allow notifications, we may store a push token and related locale information so we can deliver notification messages. You can disable notifications at any time in your device settings.

7. Subscription data

Purchases are processed by Apple through the App Store. We do not receive your full payment card details. We may receive subscription status, product identifiers, entitlement information, and transaction-related metadata needed to provide premium access.

8. Legal bases for processing

Where applicable under privacy law, we process data because it is necessary to perform our contract with you, pursue our legitimate interests in operating and improving the app, comply with legal obligations, or because you have given consent, for example for notifications where consent is required.

9. Data sharing

We may share information with:

service providers supporting app hosting, analytics, subscriptions, messaging, and infrastructure;
other users, if you intentionally share lists or links through app features;
authorities, advisers, or counterparties where required by law or to protect rights, safety, or the app.

10. International transfers

Your information may be processed in countries outside the United Kingdom or your country of residence, including where our service providers operate infrastructure. Where required, we rely on appropriate safeguards for international data transfers.

11. Data retention

We keep personal data for as long as reasonably necessary to provide the app, maintain subscriptions, resolve disputes, enforce agreements, comply with legal obligations, and support legitimate business needs. Retention periods may vary depending on the type of data and the services involved.

12. Data security

We use reasonable technical and organizational measures intended to protect information, but no method of transmission or storage is fully secure. You should also help protect your device and access credentials.

13. Your rights

Depending on your location, you may have rights to request access, correction, deletion, restriction, objection, portability, or withdrawal of consent. You may also have the right to lodge a complaint with a data protection regulator.

14. Children's privacy

Let's buy is not intended for children where collection of personal data from children is prohibited without parental authorization. If you believe a child has provided personal data in violation of applicable law, please contact us so we can review and take appropriate action.

15. Third-party privacy terms

Third-party providers may apply their own privacy terms to the data they process. You can review their policies directly for more detail about how they handle personal information.

16. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. If we do, we will publish the revised version on this page and update the "Last updated" date.
