Terms of Service

Last updated: September 8, 2026 — §7a deletion scope corrected. Prior: 2026-04-26 (path-C lock + L1+L2+L3 self-finalize amendments).

About the operator: These Terms are between you and MERIENA DIGITAL TECHNOLOGY CO., LTD. (星維數位科技有限公司), a company incorporated in Taiwan ("Operator", "we", "us", "our"). For legal service of process, contact via the email in §18 or through Google's developer-record lookup.

1. Service description

Keeva ("the Service", "the App") is a habit-tracking mobile application available on Google Play Store (Android). iOS / App Store availability is not part of the v1.0 verified launch state and applies only if Keeva later launches on iOS. Keeva is local-first: your habit data, notes, and photos are stored on your device.

Keeva is sold as a paid app on Google Play Store (Android). If Keeva later launches on iOS, the same Lifetime Edition model may be offered through the App Store. Your one-time purchase grants you the Lifetime Edition — permanent access to all features available in the version of Keeva you install (see §3 below). Future versions of Keeva may introduce new capabilities that are sold as separate optional purchases (additional one-time purchases or subscriptions); your installed-version features are never removed, restricted, or moved behind those additional charges.

Payment is processed by Google LLC (Android), not by us directly. If Keeva later launches on iOS, App Store payments are processed by Apple Inc.

2. Your age & authority

You must be at least 13 years old to use Keeva (or older where local law requires). EU users: GDPR Art. 8 sets a default minimum age of 16 for digital-services consent; some EU member states (Ireland, Spain, Portugal, Belgium, etc.) and the United Kingdom (post-Brexit retained 13) allow 13. Use whichever is higher between 13 and your jurisdiction's specific minimum. By using Keeva you warrant that you meet the applicable minimum age and have legal authority to accept these Terms.

3. Lifetime Edition — purchase, billing, scope

When you purchase Keeva (Lifetime Edition):

• One-time payment via Google Play Store for Android; App Store only if Keeva later launches on iOS
• No auto-renewal, no recurring charges, no time limit
• Pricing displayed at purchase is final for that purchase
• Payment processed by Google Play for Android; if Keeva later launches on iOS, App Store payments are processed by Apple. We never see or store your payment method

3a. Future-capability clause (anti-bait-and-switch)

Your Lifetime Edition purchase grants permanent access to all features available in the version of Keeva you install at the time of purchase, for the lifetime of the app's existence.

We may introduce new capabilities in future versions of Keeva (for example: cloud synchronization, advanced analytics, family-sharing). Such new capabilities may be offered as separate optional purchases (additional one-time IAP or subscription).

Hard guarantee: features available in your installed version shall never be removed, restricted, paywalled, or moved behind additional charge. If we ship Keeva v1.5 with cloud sync as a new optional purchase, you continue to enjoy every feature you had in your v1.0 installation, untouched, forever — only the new cloud sync capability requires the additional purchase.

This clause is a permanent commitment and survives any pricing-model change made to new users.

Sunset notice: If Keeva is discontinued or sunsetted, we will provide at least 90 days' notice on the published website (keevaapp.com) before the app ceases to be supported, allowing you to export your data via Settings → Export My Data.

3b. Pricing-model commitment on installed base

We commit that the pricing model for your Lifetime Edition purchase will not change for at least 3 years from the date of your purchase. After 3 years, model changes for new users may only be considered if:

• (a) external economic conditions fundamentally change Keeva's commercial sustainability (specifically: Apple/Google fee structure changes by ≥50%, sustained currency devaluation ≥30% in our home market, or a regulatory mandate making the current model illegal), OR
• (b) Keeva is acquired or sunsetted (operator change).

The §3a feature-availability commitment to existing Lifetime users remains permanent regardless of any such pricing-model change for new users.

4. Refunds

Refund eligibility and processing follow the app store's then-current policies and applicable law. Please use the refund channels published by the store where you purchased Keeva — Google Play for Android, or the App Store if Keeva later launches on iOS. If Google Play directs you to Keeva, send the order ID through the support email shown on the store listing for review under the applicable policy.

For Taiwan users: per 消保法 §19-1, digital-goods sales typically waive the 7-day unconditional return right. Google Play Store captures the necessary purchase consent for the Android paid-app purchase flow; if Keeva later launches on iOS, Apple App Store captures the corresponding iOS purchase consent. Keeva does not separately capture this consent. If the relevant store's flow does not satisfy 消保法 §19-1 in your jurisdiction, mandatory local law applies.

For EU users: per Consumer Rights Directive 2011/83/EU Art. 16(m), the same digital-content waiver applies once performance has begun with the consumer's prior consent.

If your purchase is refunded by the relevant app store, that store's refund process applies. A refunded purchase ends your licence to use Keeva; the store or your operating system may remove the app and its local data. If you want to keep a copy of your habit data, export it from the app before you request a refund.

5. Acceptable use

You agree NOT to:

• Reverse-engineer, decompile, or extract source from the app
• Attempt to bypass App Store / Google Play purchase requirements or any future in-app purchase restrictions
• Use the Service to harm other users or any third party
• Use the Service for illegal purposes under your local jurisdiction

6. AI / Generated Content (v1.0: NOT APPLICABLE)

Keeva v1.0 does NOT use AI to generate user-facing content. This section is reserved for future feature additions and currently states no AI content is produced.

7. Ownership of your content

You retain full ownership of all content you create in Keeva (habit titles, notes, photos, etc.). We do not claim any ownership of your content.

By using the app you grant us a limited license to process your content on your device for the purpose of providing the Service (e.g., displaying your habits, computing streaks). This license does NOT permit us to upload, share, or analyze your content on any server — Keeva is local-first by design.

7a. Your data rights

Keeva implements the following data rights for all users — exercisable directly in-app without contacting us:

• Right to access (GDPR Art. 15): all your habit data is on your device — open the Keeva app to view it
• Right to data portability (GDPR Art. 20): the app's settings include an export that produces a complete JSON copy of your data
• Right to erasure (GDPR Art. 17): You can permanently delete your habit data from the app's settings. Some settings are retained; review the confirmation before deleting. Uninstalling also removes the remaining local app data. Device backups are managed separately.

For other data rights or general privacy questions, see the Privacy Policy.

7b. Disclaimer of warranties

KEEVA IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, including any implied warranty of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that Keeva will be uninterrupted or error-free.

Keeva is not a medical device and does not provide medical, mental-health, or professional advice. Habit records, streaks, and reminders are for your own personal use and are not a substitute for advice from a qualified professional. If you use Keeva to track anything related to your health, please do not rely on it in place of that advice.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here limits any right you have under mandatory local consumer protection law.

8. Limitation of liability

To the maximum extent permitted by law:

• Our total cumulative liability is capped at the greater of (a) the total fees you have paid us for Keeva (including any future-capability purchases), or (b) US$50, whichever is greater
• Some jurisdictions do not allow these limitations; the exclusion may not apply to you in full

Specifically, we are not liable for: loss of data due to device failure (Keeva is local-first; back up your device per platform guidance); or habit-tracking accuracy (Keeva does not replace medical / health-professional advice).

These limitations do NOT apply to: (a) gross negligence or willful misconduct on our part; (b) damage to life, body, or health; (c) any liability that cannot be limited or excluded under mandatory local consumer protection law (including but not limited to TW 消保法, EU UCTD 1993/13/EEC, EU Consumer Rights Directive 2011/83/EU, and equivalent local law in your jurisdiction).

9. Indemnification

You agree to indemnify us for any claims arising from content you create in Keeva that violates third-party rights, or any use of the Service that violates these Terms.

This indemnification does not apply where prohibited by mandatory local consumer law. Specifically, EU consumers are not subject to this indemnification clause to the extent EU UCTD 1993/13/EEC or equivalent national law deems it unfair.

10. Changes to Terms

We may update these Terms. For material changes, we will:

• Publish the revised Terms at keevaapp.com/terms
• Update the "Last updated" date at the top of this page
• For users with optional future-capability purchases (if introduced), notify via the email associated with the purchase if email-bound

Continued use of the Service after notice constitutes acceptance, except that §3a feature-availability commitment and §3b pricing-model commitment are permanent and cannot be waived by continued-use acceptance — they protect your Lifetime Edition purchase regardless of subsequent Terms updates.

11. License Termination

You may end these Terms at any time by uninstalling Keeva and ceasing to use it. Because Keeva is a one-time purchase and we hold no account for you, there is nothing to cancel and nothing to notify us of. Uninstalling removes Keeva's local data from your device — export it from the app's settings first if you want to keep a copy. Ending these Terms does not entitle you to a refund; refunds follow §4.

Your license to use Keeva terminates if you materially breach §5 (Acceptable Use). For Keeva v1.0 (pure paid app), we do not perform remote entitlement checks; termination means you no longer have the right to use the app, though already-installed copies continue to function on your device until you uninstall.

We may also terminate or discontinue the Service entirely with reasonable notice (see §3a sunset notice — minimum 90 days). In either case, the §3a (feature-availability) and §3b (pricing commitment) obligations survive to the extent technically feasible.

12. Governing law & disputes

These Terms are governed by the laws of Taiwan (Republic of China). Disputes will first be resolved through good-faith negotiation. If unresolved, exclusive jurisdiction lies with the Taipei District Court, except where mandatory local consumer law of your jurisdiction grants you stronger rights — in which case those rights apply.

EU consumers: per Brussels I bis Regulation (EU) 1215/2012 Art. 17-19, you may bring claims in the courts of your EU residence; this Taiwan governing-law clause does not deprive you of mandatory protections under your home country's consumer law.

13. Severability

If any provision of these Terms is held invalid or unenforceable by a court of competent jurisdiction, the remaining provisions remain in full effect, and the invalid provision shall be interpreted to give effect, to the maximum extent allowed by law, to the parties' original intent.

14. Entire Agreement & No Waiver

These Terms (together with the Privacy Policy referenced herein) constitute the entire agreement between you and the Operator regarding Keeva. No failure or delay in exercising any right under these Terms shall operate as a waiver of that right; no single or partial exercise precludes any other or further exercise of any right.

15. Third-party services

Keeva is distributed through Google Play and relies on a small number of third-party services to function — see our third-party services page for the current list and what each one receives. Your use of those services is also governed by their own terms and privacy policies, which we do not control. We are not responsible for the availability, content, or practices of third-party services, and an interruption in one of them may affect features that depend on it. Removing or replacing a third-party service does not by itself change your rights under §3a.

16. Assignment

You may not transfer or assign these Terms. We may transfer these Terms, together with the Service, to a successor operator — for example if Keeva is acquired — and we will do so only on terms that carry over the §3a feature-availability commitment and the §3b pricing-model commitment to that successor. We will give notice of any such transfer on the published website (keevaapp.com).

17. Events outside our control

Where an event outside our reasonable control — such as a natural disaster, war, a platform or network outage, or a change in law or store policy — prevents us from meeting a notice period or other time-bound obligation in these Terms, that obligation is suspended for as long as the event continues, and we will meet it as soon as we reasonably can. This section does not reduce the §3a feature-availability commitment or the §3b pricing-model commitment, and does not apply to any liability that cannot be limited under mandatory local consumer law.
