ARCO has no server and no account. Everything stays on your iPhone. Your Screen Time data is read by Apple's framework on-device and physically cannot be exported by the app. We couldn't sell your data if we wanted to — we never have it.
ARCO is an independent iOS app built by Thinh Tran. Contact: thinht7110@gmail.com
ARCO does not have a backend server. All data you enter into the app — habits, tasks, focus sessions, schedules, app block lists — is stored locally on your iPhone using Apple's SwiftData framework. The data never leaves your device unless you back up your iPhone via iCloud, which is managed by Apple under their privacy policy.
ARCO collects no personally identifiable information. No email, no name, no phone number, no IP address, no device identifiers are sent anywhere by the app.
ARCO uses Apple's Screen Time frameworks (Family Controls + Managed Settings) to power the app blocker. When you grant Screen Time permission, iOS lets ARCO block the specific apps you select. ARCO does not learn which apps you use or what you do in them — it only holds opaque tokens for the apps you picked.
The usage statistics on the Insights screen are rendered on-device by Apple's DeviceActivityReport system, inside a sandbox that prevents the numbers from ever reaching ARCO's own code or any network. ARCO never sees or transmits this data — by Apple's design, not just our promise.
ARCO offers an optional subscription (ARCO Pro). Payment is handled entirely by Apple through the App Store — ARCO never receives your card number, billing address, or any payment details. RevenueCat, a subscription-management service, processes App Store receipts to verify your entitlement; it receives only an anonymous, randomly generated ID. See RevenueCat's privacy policy.
If you grant notification permission, ARCO schedules local notifications (morning plan, habit and task reminders, focus updates). They are created and delivered entirely on your device and never touch a server.
ARCO uses no analytics SDK (no Firebase, Mixpanel, Amplitude, or similar) and no advertising network. There is nothing to consent to under App Tracking Transparency because no tracking exists.
ARCO does not collect crash reports. If iOS prompts you to share diagnostics with developers, Apple may include anonymized crash logs under their own privacy policy.
ARCO is rated 4+ and is not directed at children under 13. ARCO does not knowingly collect any data from anyone.
Because ARCO stores nothing on any server, there is no data for us to export, correct, or delete. To remove all ARCO data, delete the app — that wipes the local database completely.
Material changes will be posted at this URL with an updated effective date. Continued use of ARCO after a change means you accept the updated policy.
