DOPA Terms of Service
Version: v1.4 Effective Date: v1.0 release (TBD) Last Updated: 2026-08-27
These Terms govern your use of the DOPA mobile application (“the App”). By installing, opening, or using the App, you agree to be bound by these Terms.
1. The Service
The App provides:
- Cognitive performance measurement (task switching, N-back, digit-symbol substitution)
- A breath pacer (Phase B Breath Pacer) for short unwinding breaks
- Self-observation visualizations (the Rhythm and Progress tabs, per-session Result)
- Local notifications at user-configured times
The App is a wellness self-observation tool. It is not a medical device and does not diagnose, treat, or prevent any disease. (See the separate Health Disclaimer: health_disclaimer_v1.md.)
2. Eligibility
You must be 14 years of age or older to use the App. The App is not directed to children. (The eligibility age is aligned with the under-14 child threshold of South Korea’s PIPA, which also satisfies the under-13 threshold of the U.S. COPPA.) If you are under 18 (or the age of majority in your jurisdiction), you should use the App only with consent of a parent or legal guardian. (See also our Privacy Policy §6 “Children”.)
The age rating set on the App Store and Google Play (12+ estimated for v1.0) reflects the presence of mental-health-adjacent content (including crisis-hotline references) and is operator-attested.
3. License to Use the App
Subject to your compliance with these Terms, the operator grants you a limited, non-exclusive, non-transferable, revocable license to install and use the App for your personal, non-commercial use.
You agree not to:
- Use the App as a basis for medical, clinical, or diagnostic decisions
- Resell, redistribute, or relicense data generated by the App, in a manner that identifies any other person
- Reverse-engineer, decompile, or otherwise attempt to derive source code from the App, except as permitted by applicable open-source licenses
- Interfere with the normal operation of the App or the App’s stores’ policies
4. Pricing
The App is free in v1.0. There are no in-App purchases, no subscriptions, no advertisements, and no paid content in v1.0. Future versions may introduce paid features only with revised Terms.
5. No Medical Advice / Emergency Use
The App is not a substitute for professional medical, psychological, or psychiatric advice, diagnosis, or treatment. Always seek the advice of a qualified health provider for any questions you may have regarding a medical or mental-health condition.
In an emergency, do not rely on the App. Contact local emergency services immediately (e.g., 911 in the United States, 119 in South Korea, 999 in the United Kingdom).
For mental-health crises in the United States: dial 988 (Suicide and Crisis Lifeline). The Health Disclaimer document lists additional regional resources.
6. Privacy
The App’s data handling is described in the Privacy Policy (privacy_policy_v1.en.md, v1.5).
By default, the App performs no outbound network transmission and stores all measurement and session data on your device. As the single exception, if you turn on the “Share anonymous usage stats” toggle in the My tab (opt-in, off by default), the App transmits anonymous usage statistics — counts per predefined event name only. Individual behavioral records, precise timestamps, user/session identifiers, and performance values (reaction times, accuracy, etc.) are never transmitted. Turning the toggle off stops transmission immediately.
For the full list of transmitted items, the cross-border transfer notice (Cloudflare, Inc., a U.S. entity), and how to withdraw consent, see Privacy Policy §2.6, §5, and §6. Opt-in consent is collected separately from these Terms via the toggle in the My tab; declining it does not limit any feature of the App.
7. Intellectual Property
The App, including all code, design, tokens, images, video assets, and audio assets, is owned by the operator or licensed under the respective open-source / Creative Commons licenses (e.g., Open Doodles character assets). Data you generate within the App belongs to you; your measurement records (reaction times, accuracy, and other per-person data) are never transmitted off your device, so the operator does not retain or process them. If you enable the opt-in toggle described in Section 6, the anonymous usage statistics transmitted are identifier-free event-name counts that cannot be linked back to you.
8. Disclaimer of Warranties
THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. THE OPERATOR DOES NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT MEASUREMENTS WILL BE ACCURATE OR FREE FROM DEFECTS.
9. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE OPERATOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY, OR ANY LOSS OF DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING FROM YOUR USE OF THE APP. BECAUSE THE APP IS FREE IN v1.0, THE OPERATOR’S LIABILITY IS LIMITED TO THE GREATEST EXTENT ALLOWED BY APPLICABLE LAW.
NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW (E.G., LIABILITY FOR GROSS NEGLIGENCE, WILLFUL MISCONDUCT, OR DEATH / PERSONAL INJURY CAUSED BY NEGLIGENCE).
10. Termination
You may stop using the App and uninstall it at any time. Uninstallation removes all on-device data.
The operator may discontinue the App with at least 30 days prior notice via the App Store / Google Play update channel or an in-App notice. Because the App’s core features (measurement, breathing, visualization) operate without a backend server, discontinuation does not retroactively delete data that you had on your device; only the opt-in anonymous-statistics ingestion server (Section 6) ceases operation.
11. Governing Law and Disputes
These Terms are governed by the laws of the Republic of Korea, without regard to its conflict-of-laws provisions. Any dispute arising out of or relating to these Terms shall be subject to the jurisdiction of the courts having jurisdiction over the user’s residence.
For users outside South Korea, this choice-of-law does not override the consumer-protection rights you may have under your local jurisdiction’s mandatory law.
Before litigating, you may apply for mediation of a consumer dispute with the Consumer Dispute Settlement Commission of the Korea Consumer Agency (www.kca.go.kr; consumer helpline 1372 within Korea). Bodies for privacy-related disputes are listed in the Privacy Policy (Korean version §9).
12. App Store / Google Play Additional Terms
If you obtained the App from the Apple App Store, you also agree to Apple’s Licensed Application End User License Agreement (LAEULA). If you obtained the App from Google Play, Google’s developer-distribution-agreement terms also apply where required.
13. Changes to These Terms
The operator may revise these Terms when there are changes to the law, the App’s features, or applicable store policies. Notice states the effective date and the reason for the revision and is given by an in-App notice, by publication on the legal-documents page (https://dopa-legal.pages.dev), or by a store update note. Material changes will be effective 30 days after notice (or 7 days for non-material changes). Continued use after the effective date constitutes acceptance. Where the notice states that you will be deemed to have accepted the revised Terms unless you object before the effective date, and you do not object by then, you are deemed to have accepted them; if you do not agree, you may terminate by uninstalling the App (Section 10). Because the App has no accounts, the operator has no means of individual notice, and the notice described here takes its place.

Version History
| Version | Date | Change |
|---|---|---|
| v1.0 | 2026-05-29 | Initial — free, on-device, non-medical wellness tool |
| v1.1 | 2026-06-12 | Reflects ADR-016 anonymous opt-in telemetry (conditional expansion) — Section 6 rewritten as default-no-transmission + opt-in anonymous statistics exception (aligned 1:1 with Privacy Policy v1.1 §2.6), Sections 7 and 10 transmission wording aligned, Appendix updated to record fulfillment of the version-bump commitment |
| v1.2 | 2026-08-11 | Section 14 contact address changed to the publisher’s own mailbox yejin255@naver.com — the previous address belonged to the Operator. Now identical to Privacy Policy v1.3 §9, security.txt v1.2, and the in-app contact link. No change to rights or obligations. |
| v1.3 | 2026-08-20 | Alignment with the shipped app (store-metadata audit F3·F4) — (1) Section 1: the retired Weekly Mirror replaced with the Rhythm and Progress tabs. (2) Section 6: opt-in consent is collected via the toggle in the My tab (the actual tab label), not a “Settings” screen. No change to rights or obligations; factual corrections only. (The Korean text additionally revised Articles 5(2) and 6(1), which had made a non-existent disclaimer-consent step a member obligation — the English text never carried that clause.) |
| v1.4 | 2026-08-27 | Upgrade against the amended PIPA and the KFTC standard terms (PIPA_2026_AUDIT_20260826.md), in step with the Korean Terms v1.5 — (1) Section 2: eligibility age 13 → 14, aligned with the Korean child threshold (COPPA 13 satisfied automatically), removing the tension with Privacy Policy §6. (2) Section 13: deemed acceptance of revised Terms when the notice says so and no objection is raised; notice content and channels stated; no-account limitation acknowledged. (3) Section 11: consumer dispute mediation (Korea Consumer Agency). (4) Section 6: Privacy Policy reference v1.5. No other change to rights or obligations. |
Appendix: Connection to ADR-014 / ADR-016 / Privacy Policy
Terms v1.0 were anchored to v1.0’s free + no-telemetry identity and committed to a Terms version bump upon telemetry adoption. Under ADR-016 anonymous opt-in telemetry (a conditional expansion of ADR-014, not a reversal), opt-in anonymous usage statistics were adopted, and these Terms were bumped to v1.1 as promised (in step with Privacy Policy v1.1). Consent to the telemetry itself is collected not through Terms re-acceptance but through the separate opt-in toggle in the My tab (off by default). Future paid features or crash reporting (Sentry — currently not adopted) will require a further Terms version bump and may require separate acceptance.
