Capture My Flag Privacy Policy

Last updated: October 30, 2026

Capture My Flag is provided by Thanh Nguyen (Sidtechs). For privacy questions or requests, contact support@sidtechs.com.

Your travel journal stays on your device

Capture My Flag stores the countries and states you mark as visited, optional dates and notes, selected HOME country and state, personal photos, and flag-unlock preferences in the app's local storage. This information supports your maps, journal, HOME display, and flag collection. You choose what to enter. Selecting HOME does not automatically mark a place as visited.

The app does not require an account and does not upload your journal or photos to Sidtechs. It does not use GPS or infer your location. Maps and flags are included with the app. The app contains no advertising or third-party analytics SDK, and Sidtechs does not sell your app data or use it for targeted advertising.

Photos you choose

You may select one personal photo for a country or U.S. state using the system photo picker. The app copies the selected image into its local journal; it does not request access to your entire photo library. It may resize the selected image. Replacing or removing the journal copy does not change the original in your photo library. When no personal photo is selected, the app displays the place's bundled flag.

Backups and sharing

Share My Travels previews a text list of places explicitly marked visited, with separate country, state and other-place counts. The list excludes photos, private notes, visit dates and HOME labels. You choose whether and where to share it through the operating system share sheet; the app does not send it automatically. The recipient and service you select receive the text you share.

When you choose Export backup, the exported file includes your travel records, notes, dates, and journal photos. The file is not password-protected or encrypted by Capture My Flag. Only save or share it with people and services you trust. Your operating system's share sheet lets you choose its destination, including a storage or cloud service if you select one. That service handles the copy under its own policies.

Import reads a backup you select. Travel backups do not grant paid purchases or transfer HOME settings, starter claims, or promotional-code records. The app does not provide automatic cloud synchronization. It is configured to exclude its journal from automatic iCloud backup and to disable Android app backup; device and operating-system behavior may vary.

Free flag collections and local preferences

All country, state and territory flags are permanently free. No purchases, starter allowances or promotional codes are required. Checkout and store purchase initialization are disabled, and no payment is taken in the app.

HOME selections and onboarding progress are kept on your device. Existing records from earlier test versions may remain in local storage, but they do not limit flag access. Clearing storage or reinstalling may reset local preferences.

Contacting support

Contact support opens your email application with our address and a subject. The app does not automatically attach photos, journal backups, device identifiers, or diagnostics. If you send an email, Sidtechs and the email services involved receive your email address, message, and anything you choose to attach. We use that information to respond and resolve your request. Please avoid sending information that is unnecessary for support.

Support correspondence is retained as needed to handle your request and any applicable recordkeeping obligations. You may request deletion by emailing support@sidtechs.com; information required for a legal obligation or unresolved dispute may need to be retained. Sidtechs cannot retrieve, correct, or delete a journal stored only on your device.

Retention and deletion on your device

Your local information remains until you change or remove it, clear app storage, or delete the app. You can edit notes and dates, change visited status and HOME selections, and remove individual journal photos. The app keeps a previous journal snapshot for recovery, and may preserve a damaged file after recovery, so removing an item from the active journal may not immediately remove every local recovery copy.

To remove all app-local records and recovery copies, clear the app's storage on Android or delete the app on iOS (offloading alone may keep data). Export first if you want to keep your journal. Backups you previously exported, original library photos, and emails you sent remain separate; delete those copies through the service or device where you stored them.

Security and external services

Local journal data is stored in the app's private storage area and relies on your device's access controls and security. Capture My Flag does not add a separate journal password or its own encryption layer. Protect your device and exported backups.

Apple, Google, your email provider, and any destination you choose for sharing may process information under their own policies. Reading this policy on sidtechs.com is a website visit: the hosting provider, Cloudflare, processes connection information such as your IP address and browser request to deliver and protect the page. This is separate from your on-device journal. See Cloudflare's privacy policy.

Changes and questions

We will update this page when the app's data practices change and revise the date above. Material new data uses will be explained in the app where appropriate. Questions about this policy or support information can be sent to support@sidtechs.com.
