Terms of Service

1. Acceptance of these Terms

Halka is created and operated by an independent, individual developer (referred to as "we", "us", or "our") — not a company or a team. By downloading, accessing, or using Halka (the "Service"), you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, please do not use the Service.

2. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your country) to use Halka. By using the Service, you represent that you meet this requirement and that you have the legal capacity to enter into these Terms.

3. The Service

Halka is an ephemeral journaling app. It provides guided breathing, a disappearing writing surface, and a sketch canvas. A defining feature of the Service is that your entries are not saved: what you write or draw fades during your session and is not stored or recoverable afterward. You acknowledge and accept that Halka is not a backup, archive, or storage service, and that you should not rely on it to retain anything you wish to keep.

4. Not medical or mental-health advice

Halka is a wellbeing and journaling tool offered for personal, reflective use. It is not a medical device and does not provide medical, psychological, or therapeutic advice, diagnosis, or treatment. It is not a substitute for professional care. If you are experiencing a crisis or thinking about harming yourself, please contact your local emergency services or a qualified professional immediately.

5. No account required

Halka does not use accounts — there is no sign-up, login, or password. You can simply open the app and begin. Any premium entitlement is tied to your Google Play account through the store, not to a profile we maintain.

6. Subscriptions, trials, and payments

Halka offers optional premium features through paid plans (for example, $2.99 / month or $9.99 one-time). Pricing and availability may change. Purchases and subscriptions are processed and managed by the Google Play store, and are subject to its terms.

• Billing & renewal. Recurring subscriptions renew automatically at the end of each billing period unless cancelled before the renewal date.
• Free trials. If a free trial is offered, any unused portion is forfeited when you purchase a subscription.
• Cancellation. You can manage or cancel your subscription at any time through your Google Play account settings.
• Refunds. Refunds are handled in accordance with the policies of the Google Play store.

7. Acceptable use

You agree not to:

• use the Service for any unlawful purpose or in violation of these Terms;
• attempt to access, probe, or disrupt the Service, its servers, or other users' accounts without authorization;
• reverse engineer, copy, resell, or create derivative works from the Service except as permitted by law;
• interfere with or circumvent any security, billing, or entitlement mechanism.

8. Intellectual property

The Service, including its software, design, text, and branding, is owned by us and protected by intellectual-property laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the Service for your own personal, non-commercial use. We claim no ownership over the private content you create — and because that content is never stored, it remains entirely yours and only yours.

9. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, or that it will meet your requirements.

10. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising out of or related to your use of (or inability to use) the Service. Because the Service is designed not to retain your entries, we are not responsible for any content that fades, is lost, or is not saved. To the maximum extent permitted by law, our total liability for any claim relating to the Service will not exceed the amount you paid us, if any, in the twelve months before the claim.

11. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, or expenses arising out of your misuse of the Service or your violation of these Terms or applicable law.

12. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you violate these Terms or if we discontinue the Service. Provisions that by their nature should survive termination (such as intellectual property, disclaimers, and limitation of liability) will survive.

13. Governing law

These Terms are governed by the laws of Vietnam, without regard to its conflict-of-laws rules. Any dispute arising out of or relating to these Terms or the Service will be subject to the jurisdiction of the competent courts of Vietnam, unless applicable mandatory law provides otherwise.

14. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date above. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
