Privacy Policy
Last updated: 28 April 2026
TL;DR
- We do not collect personal data. We do not have user accounts.
- We do not see your App Store Connect or Play Console data. Everything the extension does happens client-side, in your browser.
- We do not sell, share, or transfer any data to third parties.
- The only outbound network requests are to public data APIs (World Bank, exchange rates) and to RevenueCat for subscription verification if you upgrade to Pro.
What data the extension touches
When you open App Store Connect or Google Play Console with the StoreTune side panel active, the extension reads the price grid (territory list, current prices, currency codes, price-tier IDs) from the page. It uses this data to compute localized prices and to write the result back to the same page.
- This data never leaves your browser.
- No backend. StoreTune does not run any server-side infrastructure that receives, stores, or processes your app data. There is nothing for an attacker or rogue employee to exfiltrate, because there is no server.
- No analytics SDK. No Google Analytics, no Mixpanel, no Sentry, no Amplitude. We do not track which buttons you click or how long you spend in the side panel.
Data stored on your device
The extension uses chrome.storage.local to store:
- Your settings (base currency, PPP rounding strategy, price-tier preferences, per-app overrides)
- Cached PPP and exchange-rate data (refreshed daily)
- License state (entitlement returned by RevenueCat for Pro subscribers)
- Optional price-history snapshots (Pro feature; you can clear these any time from the side panel)
You can clear all of this by uninstalling the extension or by clicking Reset all settings in the side panel's footer.
Outbound network requests
The extension makes network requests only to the following domains, and only for the stated reason:
| Domain | Purpose |
|---|---|
api.worldbank.org | Fetch World Bank PPP conversion factors. |
open.er-api.com | Fetch current foreign-exchange rates. |
api.revenuecat.compay.rev.cat | Verify Pro-tier subscription entitlement (only if you upgrade to Pro). |
None of these requests carry your app data, your prices, or any account identifier.
Payment processing
Pro subscriptions are processed by RevenueCat via Stripe. We do not see or store your payment information. RevenueCat returns an opaque entitlement token to the extension; that's all the extension knows.
Children
StoreTune is a tool for app developers and is not directed at children under 13. We do not knowingly collect data from children.
Changes to this policy
We will update the “Last updated” date and post the new version at the same URL. Material changes will be announced in the side panel's release notes.
