  • Google AdMob (Google LLC): Device information and advertising identifiers are transmitted for ad delivery

On iOS, we may request permission for tracking under App Tracking Transparency (ATT). Even if you do not grant permission, non-personalized ads will still be displayed.

For more details, please see Google's Privacy Policy.

6. Data Storage and Security

This App is a local-first application. All user trade data is stored in a SQLite database on the user's device and is never transmitted to the Operator's servers.

  • Data entered in this App is stored on your device
  • Your personal data is not transmitted to or stored on the Operator's servers
  • Data may be lost due to device loss, malfunction, or app deletion
  • You can save your data externally using the backup feature (ZIP format) and CSV export feature
  • Your device's own backup (iCloud Backup on iOS, Google backup on Android) may include this App's database depending on your device settings. These backups are handled by Apple or Google under your account, not by the Operator. On Android, chart images are excluded from this automatic backup because of its size limit; use the in-app backup to move them to a new device
  • Backup files (.fxnote) and CSV files created by this App are not encrypted. When you save or share them (for example to cloud storage or by email), you are responsible for where they are stored and who can access them

You have the following rights regarding your information:

  • Right of Access: You can view the data you entered in this App at any time within the app
  • Right to Deletion: You can delete all data on your device by uninstalling the app
  • Advertising Opt-out: You can limit ad tracking through your device settings
  • Data Portability: You can retrieve and transfer your data using the backup feature (ZIP format) or CSV export feature

8. Children's Privacy

This App is not intended for children under the age of 13. The Operator does not knowingly collect personal information from children under 13. If we learn that personal information has been provided by a child under 13, we will promptly delete such information.

9. Changes to This Policy

The Operator may change this Privacy Policy as necessary. If there are significant changes, we will notify you through this App. If you continue to use this App after the changes, you will be deemed to have agreed to the revised Privacy Policy.

11. Users in the EEA, the UK and Switzerland

If you are in the European Economic Area (EEA), the United Kingdom or Switzerland, the following applies in addition to the sections above (GDPR, UK GDPR and the Swiss Federal Act on Data Protection).

Controller

  • The controller is MARUSOFT (Japan). Contact: app@mrym.tv or the support page.

What is processed and on what legal basis

  • Trade data you enter is processed only on your device. The Operator does not receive it.
  • Advertising (free plan): Google AdMob processes the advertising identifier, device information, IP address and app usage data. Personalized ads are shown only with your consent (Art. 6(1)(a) GDPR), which you give or refuse in the consent message shown in the App. Without consent, Google may still show non-personalized or limited ads.
  • Subscriptions: RevenueCat processes purchase information to provide the Premium Plan you bought (performance of a contract, Art. 6(1)(b) GDPR). Payments are processed by Apple or Google.
  • Support inquiries: processed to answer you (legitimate interests, Art. 6(1)(f) GDPR).

Retention

  • Trade data stays on your device until you delete it or uninstall the App. Support inquiries are kept only as long as needed to answer them. Data processed by Google and RevenueCat is kept according to their own policies.

International transfers

  • Google and RevenueCat may process data in the United States and other countries outside the EEA. These transfers rely on the safeguards those companies provide, such as the European Commission's Standard Contractual Clauses or the EU-U.S. Data Privacy Framework.

Your rights

  • You have the right of access, rectification, erasure, restriction of processing, objection and data portability.
  • You can withdraw your consent to personalized ads at any time, without affecting processing before the withdrawal, in Ad privacy settings in the App's Settings (shown in regions where consent is required).
  • Because the Operator holds no copy of your trade data, you can exercise most of these rights directly in the App: view, edit and delete records, and export them with the backup or CSV feature. For data held by Google or RevenueCat, contact us and we will help you.
  • You also have the right to lodge a complaint with the data protection supervisory authority of your country of residence or work.
