Overwater Terms of Service

Version: 1.8 | Effective: on the app's initial release date

1. Purpose

These Terms govern the conditions for using Overwater (the "App"), and define the rights, obligations, and responsibilities of the operator and users.

2. Definitions

App: refers collectively to the Overwater mobile application and the onsoonlabs.com/overwater web pages.
User: an individual who agrees to these Terms and uses the App.

3. Effect and changes

These Terms are posted in the in-app menu and on onsoonlabs.com/overwater, and take effect on the effective date shown at the top of this document. A version posted before that date is advance notice and does not take effect on its own.
The operator may revise these Terms when required by applicable law or service operations. Changes are announced at least 7 days before the effective date (30 days for material changes such as added collection items or changes in purpose of use).
Continued use of the App after a change takes effect is treated as acceptance of the revised Terms.

4. Service use

Overwater is a personal daily app that turns local weather into a single suggestion for what to do today.
The App can be used anonymously without sign-up. Core features such as weather, lifestyle advice, quick tasks, the light meter, and Wiki work without an account.
Children under 14 may use the App anonymously. The App has no in-app purchases and no subscription purchase flow.

5. User responsibilities

Weather-based lifestyle advice and AI-generated text shown in the App are general reference. Actual outcomes depend on each environment.
Final safety decisions for plants, household members (pets, children), and the user's own health rest with the user.
When official sources (forestry service, agricultural extension) provide guidance, please defer to them.
Users must not use the App in violation of these Terms or applicable law.

Restrictions on AI voice and generation features

Overwater's read-aloud voice is not recorded by a person; it is a synthetic voice generated on your device by AI, and some guidance text in plant Wiki entries is also AI-generated. Users may not use these voice or generation features, or their output (the generated voice or text), to:

violate any applicable law or regulation;
exploit or harm minors in any way;
generate or disseminate verifiably false information intended to harm others;
generate or disseminate personal information that could be used to harm an individual;
defame, disparage, or harass others;
impersonate others or create deepfakes without their consent;
distribute AI-generated voice or content without clearly disclosing that it is machine-generated;
make fully automated decisions that affect an individual's legal rights or obligations;
discriminate against or harm individuals or groups based on social behavior, personal characteristics, or legally protected characteristics;
exploit the vulnerabilities of a specific group to cause harm;
provide medical advice or interpret medical results;
assess or predict individuals in the administration of justice, law enforcement, immigration, or asylum processes.

These restrictions follow the usage terms of the on-device model used for the read-aloud voice (Supertonic-3 by Supertone, Inc., under the BigScience Open RAIL-M License). The same restrictions and the BigScience Open RAIL-M License terms also apply if the bundled model itself, or any copy extracted from the app, is used or redistributed separately. The full license text is available in the app's "Open Source & Data Sources" screen.

6. Limits of service

Overwater is solo-operated. Server maintenance, third-party API changes, and device conditions may cause temporary feature outages.
Core data is stored locally on the device first to minimize loss, but permanent retention is not guaranteed. Users are responsible for backing up important information.
The operator is not liable for damages arising from temporary interruption, change, or termination of free services.

7. Fees

Every feature of Overwater is provided free of charge. No feature, including AI-generated plant Wiki entries, carries a fee.
The App has no paid products or subscriptions for sale and no payment or purchase-restoration screens, so there are no renewal, cancellation, or refund procedures.
Any mobile data charges incurred while using the App follow the plan of the user's own carrier.

8. Privacy

The collection, use, sharing, and deletion of personal information are governed by the separate Privacy Policy.

9. Complaints and dispute resolution

For rights infringement, inappropriate content, or technical issues, please contact support@onsoonlabs.com.
Disputes related to these Terms are resolved under Korean law.
The court of competent jurisdiction for the operator's domicile shall be the court of first instance.

10. Disclaimer

The App does not guarantee the accuracy of external data (weather, plant information, AI-generated text, etc.).
Within the scope permitted by applicable law, the operator is not liable for outcomes resulting from decisions a user makes based on App guidance.

Change history

Below is the revision record of this document prior to its effective date. The Overwater Plus paid subscription that appears in earlier rows was never actually sold (no product was ever registered with the stores), and from v1.5 the app is entirely free.

Version	Effective date	Summary of changes
1.0	2026-05-14	Initial enactment. Reflected the transition to a Personal Daily App, included the Overwater Plus paid subscription, and set out the guardian-approval procedure for users under 14
1.1	2026-05-24	Reflected the first-release policy. Plus features opened free of charge; no in-app IAP or subscription purchase
1.2	2026-06-04	Removed the launch-promotion wording about opening Plus to everyone free (aligned with ADR-018, which did not adopt it). Stated Plus as a paid extension while keeping "no in-app purchase in the current version"
1.3	2026-06-21	Added the AI-synthesized-voice notice and usage restrictions for the on-device read-aloud voice (Supertonic-3, BigScience Open RAIL-M) to §5 (ADR-022 license flow-down)
1.4	2026-08-15	Reflected the removal of plant species identification — corrected "plant identification and diagnosis" in the §4 core feature list and the §5 responsibility clause to "pest and disease diagnosis," and "AI identification results" in the §10 disclaimer to "AI diagnosis results." The identification screen, server route, and external transmission path had been removed from the product, so the Terms were describing a feature that no longer existed. Changed the effective date from a fixed date to "the app's initial release date" (pinning a date before release drifts every time the launch slips — the same handling as privacy policy v2.2). Changed the publication location in §2 and §3 from overwater.app to onsoonlabs.com/overwater (the old website was retired and the canonical homepage moved). Unified the §9 and §11 contact address to support@onsoonlabs.com. Reflected the removal of pest and disease diagnosis — removed diagnosis from the §4 core feature list and corrected "diagnosis results" in §5 and §10 to "AI-generated text." The feature that sent photos to the server was gone
1.5	On the app's first release date	Reflected the confirmed move to fully free — deleted "Plus" from the §2 definitions and revised §7 from "Plus features" to "Fees," stating that the entire app is free and that no payment, subscription, or refund procedure exists. Also removed the "in the current version" qualifier in §4. Since a paid subscription was never introduced (no IAP was registered with the stores), no transitional clause for existing subscribers or refund guidance is included. Clause numbering and document structure were left unchanged
1.6	On the app's first release date	Reflected the removal of the Today LLM summary. Removed the description of the Today tab's AI briefing and listed only the AI generation paths that actually remain — the fishing summary and plant Wiki and shopping guide — in the voice/generation usage restrictions and the free-of-charge scope.
1.7	On the app's first release date	Reflected the removal of the plant shopping guide. It became unreachable after plant identification was removed, so it was deleted along with it. The shopping guide was removed from the AI generation usage restrictions (§5) and the free-of-charge scope (§7); the remaining AI generation paths, the fishing summary and plant Wiki entries, are unchanged. Users' rights and obligations are unaffected. v1.6 had not taken effect yet, but it had already been published at onsoonlabs.com/overwater/terms, so its text is left as published and this is issued as a new version.
1.8	On the app's first release date	Reflected the end of AI generation for fishing summaries. The fishing tool's copy is now derived deterministically from Korea Meteorological Administration and Korea Hydrographic and Oceanographic Agency figures, so it is no longer an AI generation path. The fishing summary was removed from the AI voice/generation usage restrictions (§5) and the free-of-charge scope (§7); the AI generation paths that remain are plant Wiki entries and the on-device read-aloud voice. Users' rights and obligations are unaffected. v1.7 had not taken effect yet, but it had already been published at onsoonlabs.com/overwater/terms, so its text is left as published and this is issued as a new version.

These Terms are written based on Korean law.
