Privacy Policy
This policy explains how APEXTENS processes personal data when you use the SunQuest mobile application, visit sunquest.app, contact us or subscribe to our communications.
Last updated: 14 September 2026
In brief. SunQuest does not require an account. Core location calculations are performed for the features you request, and saved places are primarily kept on your device. Certain service providers may nevertheless process technical, purchase, diagnostic, support or website data as described below.
1. Who is responsible for your data?
The controller is APEXTENS, a French simplified joint-stock company (SAS), SIREN 838 476 026, registered with the Paris Trade and Companies Register, whose registered office is at 128 rue La Boétie, 75008 Paris, France.
Privacy contact: contact form.
2. Data processed in the SunQuest app
Location and saved places
With your device permission, SunQuest uses your current, selected or searched location to display solar information, maps and related features. Saved places, preferences and recent app state are primarily stored locally on your device. Map and search requests may transmit coordinates, search terms, IP address and technical information to mapping providers such as Mapbox or Apple.
Purchases and app usage
To offer, validate and restore subscriptions or purchases, RevenueCat may process an anonymous app-user identifier, transaction and entitlement information, app/device technical data and attribution information. SunQuest may also send product-usage signals such as launches, feature use, paywall interactions, notification status, voluntarily supplied interests or acquisition source, and cancellation feedback. Payment card details are handled by Apple or Google and are not received by APEXTENS.
Diagnostics and security
When enabled in production, Sentry helps us diagnose crashes and errors. Reports may contain device and app information, logs, app state (including the selected location, settings and purchase state) and a screenshot captured at the time of a crash. We use this information to maintain the reliability and security of SunQuest.
Support
If you contact support, we process your email address, message and any information you choose to provide. To help diagnose a problem, the support message may include an app-user identifier, device identifier/model, operating-system and app versions, language, country and relevant settings.
3. Data processed on our website
- Site operation and security: IP address, browser/device data, requested pages, timestamps and security events may be recorded by our host and security tools.
- Forms and support: we process the contact details and message you submit.
- Newsletter: if you subscribe, we process your email address, preferences and consent record until you unsubscribe.
- Audience measurement and embedded content: where enabled, and subject to your cookie choices where required, Google services and embedded YouTube or Instagram content may place or read identifiers and receive technical usage data.
You can refuse or withdraw non-essential cookies through the consent settings displayed on the website. Essential cookies remain active where needed for security and operation.
4. Purposes and legal bases
- Providing requested app functions and managing purchases: performance of our contract and actions requested by you.
- Location access, notifications, newsletter and non-essential cookies: your consent, which you may withdraw at any time.
- Reliability, fraud prevention, security, limited product analytics and service improvement: our legitimate interests, balanced against your rights.
- Accounting, consumer and legal obligations: compliance with applicable law.
- Responding to enquiries: steps requested by you, contract performance or legitimate interests depending on the request.

These may include Hostinger (hosting), RevenueCat (subscriptions and purchase analytics), Sentry (error diagnostics), Mapbox and Apple (maps and platform services), Google (website services and YouTube), Meta/Instagram, and our email, newsletter, security and WordPress service providers.
Provider policies: Hostinger, RevenueCat, Sentry, Mapbox, Apple, Google and Meta.
6. International transfers
Some providers may process data outside the European Economic Area, particularly in the United States. Where required, transfers are covered by an adequacy decision, the EU–US Data Privacy Framework for participating organisations, Standard Contractual Clauses or another valid safeguard.
7. How long we keep data
| Data | Typical retention |
|---|---|
| Locally saved places and preferences | Until you delete them, reset the app or uninstall it. |

| Website and security logs | For a limited period appropriate to operation and security, according to hosting and security configuration. |
Provider-side records may be retained for additional periods required by law or described in the relevant provider policy.
8. Your rights
Subject to the GDPR and applicable law, you may request access, correction, deletion, restriction, portability or objection, and withdraw consent at any time. You may also give instructions regarding your data after death where French law permits.
Contact contact form. We may ask for information necessary to verify your identity. You may lodge a complaint with the CNIL or your local supervisory authority.
9. Children
SunQuest does not require an account and APEXTENS does not knowingly seek personal information from children. Parents or guardians may contact us to exercise rights regarding a child’s data.
10. Security and changes
We use reasonable technical and organisational safeguards appropriate to the data and risks involved. No online service can guarantee absolute security. We may update this policy when the app, website, providers or law changes; the date above identifies the latest version.
