ITTEKI
Privacy Policy

Pick how you feel and one line of words falls to you. The app collects no personal information and never connects to the internet.

// summary Summary

  • No personal information is collected. There is no account or sign-in.
  • No internet connection. The App has no networking capability and sends nothing anywhere.
  • The only things stored are the words you starred, the notes you added, which words have been shown, and your display language — all on your device.
  • There are no advertising, tracking, analytics or crash-reporting SDKs. No notifications.

01 Operator

02 Information handled

The App does not collect personal information. It does not access your name, email address, location, device identifiers, contacts, photos, or anything else that could identify you.

The App handles only the following, all stored on the device only and never transmitted.

The feeling you pickThe feeling you tap (five levels) and the time of day are used to choose a line. Feelings are never listed or charted; a starred line simply carries the mark of the feeling you picked at the time
Stars and notesThe lines you starred and any note you added (optional)
Shown historyA record of which lines have been shown, so the same line is not repeated
Display languageJapanese or English

These are deleted from the device when you uninstall the App. Stars and notes can be removed in the App at any time.

03 Network

The App never connects to the internet. All of its lines are bundled with the App and it contains no networking code. No usage data, settings or other information is sent to us or to any third party. Every feature works in airplane mode.

The "About ITTEKI", "Privacy Policy" and "Made by" links on the info screen open our websites in the device's browser only when you tap them. The App itself does not communicate.

04 Advertising, tracking and analytics

The App shows no advertising. It includes no advertising, tracking or analytics SDKs (including Firebase Analytics and Crashlytics) and never sends usage or crash data to us or to third parties.

Because the App does nothing that falls under iOS App Tracking Transparency (ATT), no tracking prompt is shown.

05 Device features and permissions

The App uses no device features that require permission — no location, camera, microphone, photos, notifications or contacts. It sends no notifications.

06 About the words

The lines in the App are either written by us (ITTEKI) or chosen from sources whose copyright has expired. Translations were made for the App from the original text. The source is shown beneath each line.

07 Disclosure to third parties

We do not disclose information to third parties except in the following cases:

  • With your consent
  • Where required by law
  • Where necessary to protect a person's life, body or property and it is difficult to obtain your consent

08 Children's privacy

The App is not directed at any particular age group and does not actively collect personal information from anyone. If a child uses the App, please do so under a parent's or guardian's supervision.

09 Changes to this policy

We may revise this policy when laws change or features are added. Material changes will be announced on this page or on the App's store page. The revised policy takes effect when it is posted here.

10 Contact

For questions about this policy or the handling of personal information, please contact office@res.co.jp.
