Furigana Memo Privacy Policy
QuickServe Inc. ("we", "us") sets out below how user information is handled in Furigana Memo (the "App"), our note-taking app for adding furigana (ruby text) to text (this "Policy").
1. Company information (data controller)
- Name: QuickServe Inc.
- Address: Sakurai Bldg. 2F, 2-8-19 Fukagawa, Koto-ku, Tokyo 135-0033, Japan
- Contact: info@91932.com / Tel. +81-3-6450-5141 (weekdays 10:00–19:00 JST)
- Personal data protection manager: Manager, Systems Development Department
Where the GDPR or similar laws apply, QuickServe Inc. is the data controller for the App.
2. Scope and authoritative version
This Policy applies only to the App. Our other apps are covered by our common app privacy policy. This document is independent of the privacy policy on our corporate website. The Japanese version of this Policy is authoritative; if there is any discrepancy with a translation, the Japanese version prevails.
3. Information the App stores on your device
The App can be used without creating an account, and we do not directly collect your name, email address or similar information. The data below is stored only in a database on your device and is never sent to our servers. We cannot access this data.
| Data | Source | Purpose |
|---|---|---|
| Memos (title, body text, created/updated timestamps, pinned status, deletion status) | Entered by you | Displaying, editing, searching, sorting and trash management for memos |
| Manual ruby (furigana you add to a selected range of text in a memo) | Entered by you | Displaying furigana in that memo and converting it on export |
| Folder structure | Entered by you | Organizing and listing memos |
| Word groups (word-and-reading pairs registered as a furigana dictionary) | Entered by you | Adding furigana automatically |
| Assignment of word groups to folders | Your actions in the App | Managing which folders receive automatic furigana from which word groups |
| App settings (theme, font size, display language, sort order, ruby-notation export format, PDF export options, etc.) | Your actions in the App | Retaining your display and behavior preferences |
| Premium status (whether you have purchased premium, and the expiry of a reward obtained by watching a video ad) | Generated by the App | Hiding ads and providing the PDF export feature (Sections 5 and 7) |
| Operation log (an internal log file) | Generated by the App | A record you can inspect yourself if a problem occurs. It is never sent to us |
You can delete this data through actions in the App (deleting memos, folders or word groups, etc.), and uninstalling the App removes it from your device. Content you enter — memo titles and body text, furigana, folder names and so on — is never sent to the third-party SDKs described in Section 4.
4. Information collected and transmitted by third-party SDKs
The App uses the following third-party SDKs for advertising and quality improvement. These SDKs automatically collect the information below and transmit it to servers operated by Google LLC and its affiliates ("Google").
| SDK | Main information collected | Purpose |
|---|---|---|
| Google AdMob (ad serving) | Advertising ID (iOS: IDFA / Android: Advertising ID; collected only where permitted by OS settings, applicable law, and your consent choices), ad impression and interaction events, IP address (including approximate location estimation), device information (model, OS version, etc.) | Serving ads, measuring ad performance, fraud prevention |
| Firebase Crashlytics (crash reporting) | Crash logs, diagnostic information, installation UUID, device, OS and app version information | Analyzing defects, improving stability * Active only in store-distributed builds |
| Firebase Analytics (usage analytics) | Identifiers such as the app instance ID, screen views and counts of feature usage (PDF export, ruby-notation export and import, manual ruby, obtaining a reward by watching a video ad), device and OS information, approximate region based on IP address | Improving the App through usage analysis * Disabled by default (Section 9) |
Firebase Analytics records only predefined screen names, feature names and their counts. Text you enter, such as memo content or the contents of word groups, is never included in these events.
When you contact us, we collect your contact details (such as name and email address), the content of your inquiry, and, where necessary, device/OS information, for the purpose of responding to your inquiry. This information is deleted after a reasonable period following the completion of our response.
5. Advertising in the App
The App displays a banner ad on the memo list, memo editor, word group and settings screens. In addition, you may choose to watch a video ad (a rewarded ad); doing so hides ads and unlocks the PDF export feature for 24 hours. Watching is entirely optional, and all other features of the App remain fully available if you do not.
In place of a Google AdMob ad, the banner slot may show a promotion for one of our other apps. Such a promotion only displays information we have prepared (app name, description, icon and a link to the store) and involves no collection or transmission of information about you.
Ads are served by Google AdMob. The advertising providers Google uses as partners are listed in Google's ad technology providers. Personalized advertising is carried out only in accordance with applicable law and your consent or permission choices (iOS ATT, and the consent form in the EEA and the UK). Where consent or permission has not been given, non-personalized (limited) ads that do not use the advertising ID are served instead.
6. External transmission
The only data the App transmits externally without action by you is the third-party SDK information described in Section 4. We operate no server of our own, and your memo content is never sent to us.
In addition, to show the promotions for our other apps described in Section 5, the App periodically retrieves the promotion information (app name, description and icon) from our website (qkserve.github.io, hosted on GitHub Pages operated by GitHub, Inc.). As with viewing any web page, connection information such as your IP address reaches GitHub's servers during this retrieval; we do not collect or store it, and none of your activity or memo content is transmitted.
The "share", "export" and "PDF export" features only pass the converted text or file to the OS share sheet (the screen where you choose a destination app); whether and where it is sent from there is entirely your own choice and action. We never receive the content of anything you share or export.
7. In-app purchase
The App offers a one-time (non-consumable) in-app purchase, "premium", which permanently removes ads and unlocks the PDF export feature. Payment is processed by the Apple App Store or Google Play, and we never receive your credit card number or other payment details. Your purchase status is stored on your device; after changing devices or reinstalling, you can restore it through your store account from "Settings > Premium > Restore purchases". Purchase history, refunds and related matters are handled in accordance with the privacy policies and terms of the respective store providers (Apple / Google).
8. How backups are handled
The App has no cloud-sync or backup feature of its own. On Android, automatic backup is disabled, so the App's data is not backed up to Google's servers. On iOS, if your device's iCloud Backup is enabled, a copy of the App's data may be stored on Apple's servers and restored when you reinstall. This copy remains even after you delete the App, so please remove it from your iOS backup settings if you no longer need it. If we add our own cloud-sync or backup feature in the future, we will revise this Policy and post a notice on this page.
9. Managing consent / opting out
- iOS (ATT): You can choose whether to allow tracking in the ATT dialog shown on first launch, and change your choice at any time in iOS Settings > Privacy & Security > Tracking. If tracking is not allowed, neither we nor Google will use the IDFA to track you across apps.
- Regions where consent is required (EEA, UK, etc.): A consent form is displayed through Google's consent management platform (UMP). You can change or withdraw your consent at any time from "Settings > Privacy > Ad consent settings" in the App (shown only in applicable regions). Withdrawal of consent does not affect the lawfulness of processing carried out before withdrawal.
- Usage analytics (Firebase Analytics): Collection is disabled by default and is enabled only for users in regions where consent is not required. For users in the EEA, the UK and other regions where consent is required, no usage data is collected regardless of the choices made in the consent form. All Google Consent Mode defaults are set to "denied".
- Supplementary OS settings: On Android you can reset or delete your Advertising ID in Settings > Privacy > Ads; on iOS the tracking setting above applies (neither is itself a withdrawal of consent).
10. Provision to third parties
We do not provide collected information to third parties, except as required by law and except for transmission to the external service providers described in this Policy (Google and Apple).
Information transmitted through the SDKs described in Section 4 is handled by Google in accordance with its privacy policy. Depending on the nature of the processing, Google may process the information as an independent controller.

- How Google uses information from sites or apps that use its services
- Privacy and Security in Firebase
- Apple Privacy Policy (in-app purchase)
11. International data transfers
The destinations of the SDK transmissions described in Section 4 include Google servers located in the United States and other countries outside Japan. Google implements appropriate safeguards, including compliance with the EU Standard Contractual Clauses (SCCs). Details of transfer destinations and safeguards are available in "Privacy and Security in Firebase" linked above. The on-device data described in Section 3 is not subject to any such transfer.
12. Additional information for users in the EEA and the UK (GDPR / UK GDPR)
The legal bases for processing are as follows.
| Processing | Legal basis |
|---|---|
| Storing/reading identifiers on the device (advertising ID, etc.) | Consent |
| Serving personalized ads | Consent |
| Serving ads without consent (limited ads), fraud prevention | Legitimate interests (keeping the App free of charge, security) |
| Crash reporting (Crashlytics) | Legitimate interests (quality assurance based on data minimization) |
| Providing and restoring in-app purchases | Performance of a contract |
| Responding to your inquiries | Steps taken in connection with responding to your inquiry, or our legitimate interest in providing an appropriate response |
| Compliance with legal obligations | Legal obligation |
As described in Section 9, usage analytics (Firebase Analytics) is not carried out for users in the EEA and the UK.
- Access to data on your device: You can view, edit and delete your memos, word groups, folders and settings at any time directly in the App.
- Retention: For the retention periods of data collected by Google, see Privacy and Security in Firebase and Google's advertising policies. Retention of inquiry information is described in Section 4.
- Your rights: You have the rights of access, rectification, erasure, restriction of processing, objection and data portability. You can exercise these rights through the contact point in Section 15.
- Complaints: You have the right to lodge a complaint with the supervisory authority in your country.
- Voluntariness: Providing information is neither a contractual nor a statutory requirement, and you can use the App without providing it (this may affect the ads displayed).
- Automated decision-making: We do not carry out automated decision-making, including profiling, that produces legal effects.
13. Users in other regions
Depending on the laws of your region (such as US state laws), you may have rights such as access, deletion and opt-out. You can exercise these rights through the contact point in Section 15.
14. Children
The App is not designed for or directed at children under 13, and we do not knowingly collect personal information from children under 13.
15. Requests for disclosure and contact point
Requests for disclosure, correction, suspension of use or deletion of retained personal data, and enquiries about this Policy, are accepted at the contact point below. We may ask you to present identification documents. There is no fee.
