Privacy Policy
Last updated: 31 May 2026
ChartBuddy is operated by Noesis Trading Co. Ltd (“we”, “us”). This policy describes what data the ChartBuddy mobile application collects, how it is used, and the rights you have.
Summary in one line
ChartBuddy is a fully local app. We do not ask you to create an account, and we never see or store your personal information. Your progress, streaks, saved topics, settings, and quiz scores all live on your device only.
What ChartBuddy does NOT collect
For clarity, we do not collect any of the following:
- Your name, email address, phone number, or any other contact details.
- Your location, IP address, or browsing history.
- Your trading activity, brokerage credentials, or any financial data.
- Photos, contacts, files, or microphone audio.
- Any information about other apps installed on your device.
What is collected by the services we use
ChartBuddy itself runs entirely on your device, but three third-party services receive limited, anonymous data to do specific jobs. None of this data identifies you personally, and none of it is shared with us in identifiable form.
RevenueCat (in-app purchase verification)
When you tap “Unlock ChartBuddy” or “Restore Purchases”, RevenueCat receives an anonymous app-scoped device identifier so it can verify your one-time purchase and unlock the app for you. They do not receive your name, email, or any other personal information. See revenuecat.com/privacy.
Apple App Store / Google Play (payment processing)
Your actual payment is processed by Apple or Google. We never see your payment details. Refer to Apple's privacy policy and Google's privacy policy for details on how each store handles payments.
Meta (app-promotion advertising)
ChartBuddy includes the Meta SDK so we can measure the effectiveness of any Facebook or Instagram ads we run to find new users. Meta receives anonymous app-scoped events (for example, that the app was opened, that the paywall was viewed, or that a one-time purchase was completed) and an anonymous device identifier. We deliberately do not enable cross-app tracking. See Meta's privacy policy.
Children
ChartBuddy is not directed at children under 13 and we do not knowingly collect any data from them. The minimum age to use the app is 13.
Your rights
You can delete all your local data at any time from inside the app: Settings → “Delete all my data”. This permanently erases your progress, streaks, saved topics, quiz scores, and settings on your device. Your one-time purchase is not affected and can be restored at any time using the “Restore Purchases” button.
Changes to this policy
We may update this policy occasionally. Material changes will be reflected by an updated date at the top of the page. Continued use of the app after a change constitutes acceptance of the updated policy.
