These Terms of Service (“Terms”) govern your access to and use of the Hakoi mobile application and related services (collectively, the “Service”) operated by Journeye (“we,” “us,” or “our”). Hakoi is a habit-tracking application available on Android, iOS, and other platforms.

By creating an account, downloading, installing, or otherwise using the Service, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the Service. We may update these Terms from time to time, and your continued use of the Service after any changes constitutes acceptance of the revised Terms.

2. Definitions

“Account” means a registered user account created to access the Service.
“Content” means any data, text, information, or other materials you create, upload, or store through the Service, including habit data, notes, categories, and profile information.
“Hakoi Plus” and “Hakoi Premium” refer to paid subscription tiers offering additional features.
“Karma” refers to the in-app gamification point system.
“Contract” refers to the accountability feature allowing users to enter mutual habit commitments with other users.

3. Eligibility

You must be at least 13 years of age to use the Service. If you are between the ages of 13 and 18 (or the age of majority in your jurisdiction), you may only use the Service with the consent of a parent or legal guardian who agrees to be bound by these Terms on your behalf.

By using the Service, you represent and warrant that you meet these eligibility requirements.

4. Account Registration and Security

4.1 Account Creation

To access certain features of the Service, you must create an Account using one of the following methods: email and password, magic link (one-time password), Google sign-in, or X (Twitter) sign-in.

You agree to provide accurate, current, and complete information during registration, and to keep this information updated.

4.2 Account Security

You are responsible for maintaining the confidentiality of your Account credentials and for all activities that occur under your Account. You agree to notify us immediately of any unauthorized use of your Account or any other breach of security.

We are not liable for any loss or damage arising from your failure to protect your Account credentials.

4.3 One Account Per User

Each user may maintain only one active Account. We reserve the right to merge or terminate duplicate accounts.

5. Use of the Service

5.1 License Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the Service on devices you own or control, for your personal, non-commercial use.

5.2 Acceptable Use

You agree not to:

Use the Service for any unlawful purpose or in violation of any applicable laws or regulations.
Impersonate any person or entity, or falsely state or misrepresent your affiliation with any person or entity.
Interfere with or disrupt the Service, servers, or networks connected to the Service.
Attempt to gain unauthorized access to the Service, other user accounts, or computer systems or networks connected to the Service.
Use automated means (bots, scrapers, crawlers) to access, collect data from, or interact with the Service without our express written permission.
Reverse engineer, decompile, disassemble, or attempt to derive the source code of the Service.
Transmit any viruses, worms, defects, trojan horses, or other items of a destructive or harmful nature.
Harass, abuse, stalk, threaten, or otherwise violate the rights of other users.
Use the social features (Contracts, Leaderboard, Karma sharing, friend system) to bully, intimidate, or engage in toxic behavior toward other users.
Manipulate or exploit the Karma system, Leaderboard rankings, or Contract system through fraudulent or dishonest means, including but not limited to: creating duplicate accounts to inflate Karma, falsifying habit completion data, artificially inflating Leaderboard rankings, or colluding with other users to game the scoring system.
Upload or share Content that is defamatory, obscene, hateful, or otherwise objectionable through any user-facing fields (usernames, habit notes, etc.).

5.3 Content Responsibility

You are solely responsible for all Content you create or store through the Service. We do not claim ownership of your Content, but you grant us a limited license to host, store, back up, and display your Content as necessary to provide the Service.

6.1 Public Profile

The Service includes optional social features including a Leaderboard, Contracts (accountability partnerships), a Karma system, and user profiles. If you enable a public profile, certain information (such as your username, Karma score, and Leaderboard ranking) may be visible to other users.

6.2 Contracts

Contracts are mutual, voluntary agreements between users to complete habits together. Either party may withdraw from a Contract at any time. Contracts are informal accountability tools and do not constitute legally binding agreements between users.

You agree to interact with other users respectfully. We reserve the right to ban or restrict users who engage in harassment, abuse, or manipulation of social features. A banned user’s profile and social features may be disabled.

7. Subscriptions and Payments

7.1 Subscription Tiers

The Service offers free and paid subscription tiers (Hakoi Plus and Hakoi Premium). Paid subscriptions provide access to additional features as described in the Service.

7.2 Billing

Paid subscriptions are managed through RevenueCat, which processes billing through the Google Play Store and Apple App Store. The actual payment transaction is handled by the respective platform and is subject to their terms of service and payment policies. RevenueCat manages subscription state, entitlement verification, and renewal logic on our behalf.

7.3 Free Trial

We may offer free trial periods for paid subscriptions. If you do not cancel before the trial period ends, your subscription will automatically convert to a paid subscription and you will be charged the applicable subscription fee.

7.4 Renewal and Cancellation

Subscriptions automatically renew at the end of each billing period unless you cancel before the renewal date. You may cancel your subscription at any time through the app store where you made the purchase (e.g., Google Play Store settings or Apple App Store settings). Cancellation takes effect at the end of the current billing period; you will retain access to paid features until that period expires.

7.5 Refunds

Since billing is processed through RevenueCat and the respective app stores, refund requests must be directed to Google Play or Apple App Store support in accordance with their refund policies. We do not process refunds directly and have no ability to issue refunds on transactions handled by the app stores.

7.6 Offline Grace Period

If the Service cannot verify your subscription status due to connectivity issues, a grace period of up to 7 days is provided during which you will retain access to paid features. After this grace period expires without successful verification, your account will automatically revert to the Free tier. No additional charges are applied during the grace period. Once connectivity is restored and your subscription is re-verified, paid features will be restored immediately.

7.7 Price Changes

We reserve the right to change subscription pricing at any time. Price changes will take effect at the start of the next billing period following notice of the change. Your continued use of the paid subscription after a price change constitutes acceptance of the new price.

8. Data and Backups

8.1 Local Data

The Service stores your Content locally on your device in an encrypted database. You are responsible for maintaining your device and ensuring its security.

8.2 Cloud Backups

The Service provides cloud backup functionality through Supabase. You may create manual backups or enable automatic backups (daily, weekly, or monthly). Backups include your categories, habits, habit instances, reminders, and timer entries.

8.3 Data Loss

While we take reasonable precautions to protect your data, we do not guarantee against data loss. You are encouraged to use the backup feature regularly. We are not liable for any loss of Content due to device failure, software errors, server issues, or any other cause.

9. Intellectual Property

9.1 Our Intellectual Property

The Service, including its design, graphics, interfaces, code, and all related intellectual property, is owned by us or our licensors and is protected by copyright, trademark, and other intellectual property laws. Nothing in these Terms grants you any right to use our trademarks, logos, or branding without our prior written consent.

9.2 Your Content

You retain ownership of the Content you create through the Service. By using the Service, you grant us a worldwide, non-exclusive, royalty-free license to use, host, store, reproduce, and display your Content solely for the purpose of operating, maintaining, and providing the Service to you.

9.3 Feedback

If you provide us with feedback, suggestions, or ideas regarding the Service, you grant us an unrestricted, irrevocable, perpetual, royalty-free license to use such feedback for any purpose without compensation or attribution to you.
