1. Introduction
Codoha Ltd. ("Codoha," "we," "our," or "us") operates the ATC Radio Sim Android application (the "App"). Codoha Ltd. is registered in Taiwan (R.O.C.) at Rm. 5, 4 F., No. 8, Guomin 8th St., Hualien City, Hualien County 970015, Taiwan (R.O.C.). This policy explains what information the App uses and why.
2. Summary
The App has no user account, advertising or third-party analytics. Voice play sends a short recording of what you said to Codoha, which has it transcribed and uses the resulting text for that one radio call. Neither the recording nor the text is retained. Offline mode uses your phone’s own speech recogniser instead, so nothing leaves the device. The App also uses limited installation and integrity records to operate the service and prevent abuse.
3. Microphone, Audio and Transcripts
The App asks for microphone access only after showing an in-app explanation and receiving your action, and it states before that point whether recognition happens on your device or in the cloud. On Android, push-to-talk records a short, length-limited clip and sends it over an encrypted connection to Codoha’s gateway, which passes it to a speech provider for transcription and returns the text to the App. That text is then interpreted for the current radio call. Codoha does not retain the recording or the recognised text, and writes neither to its application database or logs; AI requests use zero-data-retention routing. On the web build there is no such upload: the browser speech service performs recognition under its own privacy terms and only text reaches Codoha. Turn on offline mode in Settings and the App uses your phone’s own recognition service, so no audio and no transcript leave the device. You can use the touch controls or the text box instead of the microphone at any time.
4. Information Stored on Your Device
The App stores game progress, settings, selected airport, difficulty and shift length, offline-mode and voice preferences, recogniser and calibration values, microphone labels, allowance state and an installation identity in private app storage. It does not save what you said or a history of recognised transcripts. Clearing the App’s Android data or uninstalling it removes this local information. Android may include app data in a backup that you control through your device or Google account settings.
5. Service and Anti-Abuse Records
To provide cloud play without requiring an account, our service stores an opaque installation identifier and public key, app and platform versions, timestamps, allowance counters, request and estimated spend totals, attestation results and minimal service diagnostics. These records are used to authenticate requests, enforce the free allowance, secure the service, investigate faults and prevent repeated abuse. They are not used for advertising or cross-app tracking.
6. Google Play Integrity and Device Recall
Android releases may use Google Play Integrity to check whether requests come from the genuine App on a trustworthy installation. We may also use one Device Recall bit to remember that a device has already received its one free allowance, even after reinstall. Google provides the integrity verdict; Codoha does not receive your Google account or payment details through this check.
7. Retention and Deletion
Codoha does not retain player recordings, by default or otherwise, and does not keep recognised transcripts after the request they belong to. The free allowance is five cumulative hours of live-world play per installation, and the counters tracking it are part of the installation record described above. Cached pilot voice lines are generated game content, never player speech, and may be kept for up to 90 days. Service audit events are kept for up to 90 days. Inactive installation records are kept for up to three years after last use, and an anti-abuse Device Recall value may remain available for up to Google’s supported three-year period. You can use Settings > Delete cloud data to send an authenticated deletion request for Codoha’s records for that installation; deleting them does not reset the allowance or grant another one, and your local progress stays on the device. Clear the App’s data or uninstall it to remove local records.
8. Service Providers and Transfers
On Android, Codoha’s gateway passes your recording to a speech-to-text provider for transcription and receives text back. On the web, the browser or operating system speech service performs that step under its provider’s terms. We use Cloudflare for application delivery, request handling and database infrastructure; OpenRouter and compatible model providers for interpretation of the recognised text and for generated pilot speech; and Google Play™ services for app distribution and integrity checks. These providers may process data in countries outside your own under their respective privacy terms and safeguards. We do not sell personal data or share it for behavioural advertising.
9. Security
We use encrypted transport, signed installation requests, integrity checks, access controls and data minimisation. No system is perfectly secure, but we limit what is stored so that sensitive voice content is not part of the retained service record.
10. Your Privacy Rights
Depending on where you live, you may have rights to access, correct, delete, restrict or object to processing of personal data, or to receive a portable copy. The in-app deletion control handles the cloud record for the current installation. You may also contact us for assistance or complain to your local data protection authority. Because the App has no account and stores only an opaque installation identity, we may need information from the signed installation to locate a record and may be unable to connect other information to you.
11. Children's Privacy
The App is intended for users aged 13 and over and is not directed to children under 13. If you believe a child has provided personal information through the App, contact us so we can investigate and delete it where applicable.
12. Changes to This Policy
We may update this policy as the App changes. The current version and its effective date will remain on this page. Material changes will also be called out in the App or its store listing when appropriate.
