Welcome to Chrona. These Terms of Service ("Terms") govern your access to and use of the Chrona mobile application, related websites, and services (collectively, the "Service"), currently operated by Laurens Surya and Denny Ryanto, individual co-founders operating the Service pending formal incorporation ("Chrona," "we," "us," or "our").
By downloading, accessing, or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Service.
1. Description of the Service
Chrona is a social scheduling application designed to help tight-knit communities, such as run clubs, sports circles, campus groups, and similar groups, plan and coordinate time together. Core features include shareable invite links, group scheduling tools, calendar sync, AI-assisted planning, and notifications delivered via push notification and via link previews rendered on WhatsApp. Chrona is currently offered as a minimum viable product (MVP), and features, availability, and functionality may change, be added, or be removed at any time without notice.
2. Eligibility
You must be at least 16 years old (or the minimum age of digital consent in your jurisdiction, if higher) to create a Chrona account. By using the Service, you represent that you meet this requirement and have the legal capacity to enter into these Terms. If you use the Service on behalf of a group, club, or organization, you represent that you have authority to bind that group to these Terms with respect to its use of shared features.
3. Accounts & Registration
- Chrona accounts are currently created and verified using your mobile phone number.
- You are responsible for maintaining the security of your device and account, and for all activity that occurs under your account.
- You agree to provide accurate information and to promptly update it if it changes.
- We reserve the right to suspend or terminate accounts we reasonably believe are fraudulent, abusive, impersonating another person, or otherwise in violation of these Terms.
4. Invite Links, Groups & Shared Content
- Chrona lets you generate shareable invite links, which may render preview cards (including images and event details) when shared on WhatsApp or other third-party platforms.
- You are responsible for the audience with whom you share an invite link. Anyone who receives a link may be able to view the associated preview information unless you use the privacy settings the app makes available.
- Group organizers are responsible for moderating their own groups and for obtaining any consent needed from members before adding them, sharing their information, or uploading their photos within the Service.
5. User Content & Conduct
"User Content" means any information, text, photos, event details, or other material you submit to or through the Service. You retain ownership of your User Content. By submitting User Content, you grant Chrona a worldwide, non-exclusive, royalty-free, sublicensable license to host, store, reproduce, display, and distribute it solely as necessary to operate, maintain, and improve the Service (for example, generating an invite-link preview card). You represent that you have all rights necessary to submit your User Content and that it does not infringe any third party’s rights.
You agree not to:
- use the Service for any unlawful purpose or to harass, threaten, defame, or impersonate any person;
- upload content that is obscene or hateful, or that infringes the intellectual property or privacy rights of others;
- upload photos or personal information of another person without their consent;
- attempt to gain unauthorized access to the Service, other accounts, or our systems;
- reverse-engineer, decompile, or scrape the Service, or interfere with its normal operation;
- use the Service to send spam, unsolicited mass invites, or malicious links.
We may remove User Content or suspend accounts that violate this section, though we are not obligated to monitor content and are not responsible for User Content posted by other users.
6. Intellectual Property
The Service, including its design, brand elements (including the Chrona name, wordmark, and C-Mark), software, and underlying technology, is owned by Chrona and its licensors and is protected by intellectual property laws. Except for the limited license to your own User Content described above, nothing in these Terms grants you any right to use Chrona's trademarks, logos, or brand assets without our prior written consent.
7. Third-Party Services & AI Features
7.1 Sharing on WhatsApp. Chrona lets you share an event invite link on WhatsApp, for example by using your device's native share function or by pasting the link into a chat. Chrona does not integrate with the WhatsApp Business API or otherwise connect to WhatsApp on your behalf. When a link you share is opened, WhatsApp's own systems may fetch publicly available preview information associated with that link (such as an event title and image) to render a link preview. This is standard behavior for any link shared on WhatsApp, and it does not involve us transmitting your personal account data to WhatsApp or Meta Platforms, Inc. Your use of WhatsApp remains subject to WhatsApp's own terms and privacy policy.
7.2 AI-Assisted Features. Chrona offers AI-assisted scheduling and chat-based planning features (for example, suggesting event times or helping you and your group plan together), powered by Google's Gemini models, which we access through Google Cloud Vertex AI. These features are configured to focus on scheduling- and event-planning content, but they process the free-form text you choose to enter, which may include event details, names, or other context about you or the people you're planning with, as well as availability information from any calendar you've connected. AI-generated suggestions may be inaccurate, incomplete, or unsuitable for your situation, and you are responsible for reviewing them before relying on them, including when making plans with others. You agree not to enter information about another person into an AI feature unless you have the right to share it. See our Privacy Policy for more on how this data is handled.
7.3 Hosting & Notifications. The Service also relies on Firebase Cloud Messaging and Google Cloud Platform (Google LLC) for hosting and push notifications, subject to Google's own terms and policies.
Your use of any third-party platform referenced in this Section is subject to that platform's own terms and privacy policies, and we are not responsible for its availability, content, or practices.
8. Connected Calendars
Chrona lets you connect a third-party calendar (currently Google Calendar or Apple Calendar) to help you and your group find times that work. Connecting a calendar is optional and requires your separate authorization with that provider, and your use of it remains subject to that provider's own terms. Chrona's access to a connected calendar is currently read-only: we read your existing events to check availability and suggest times, and we do not create, modify, or delete events on your connected calendar. You can disconnect a calendar at any time in the app's settings. See our Privacy Policy for how calendar data is used and retained.
9. Fees
The Service is currently offered free of charge, and we do not currently process payments through the Service. If we introduce paid features, subscriptions, or in-app purchases in the future, additional terms governing pricing, billing, and cancellation will be presented to you and, upon your acceptance, will supplement these Terms.
10. Disclaimers
AI-Generated Content. Certain features of the Service use artificial intelligence, including Google's Gemini models accessed through Google Cloud Vertex AI, to generate suggestions, proposed schedules, or other content. AI-generated content may be inaccurate or incomplete. We do not warrant its accuracy, and you are responsible for independently verifying it before relying on it or acting on it.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. AS AN EARLY-STAGE MVP, THE SERVICE MAY CONTAIN BUGS, EXPERIENCE DOWNTIME, OR CHANGE SIGNIFICANTLY WITHOUT NOTICE. WE DO NOT GUARANTEE THE ACCURACY OF EVENT INFORMATION, SCHEDULES, OR CONTENT SUBMITTED BY USERS, AND WE ARE NOT RESPONSIBLE FOR THE CONDUCT OF ANY USER, ONLINE OR OFFLINE, INCLUDING AT ANY EVENT OR MEETUP ORGANIZED THROUGH THE SERVICE.
11. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CHRONA, ITS FOUNDERS, CONTRACTORS, AND AFFILIATES WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES ARISING FROM YOUR USE OF, OR INABILITY TO USE, THE SERVICE. OUR AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS PRECEDING THE CLAIM, OR (B) IDR 1,000,000 (OR THE EQUIVALENT IN LOCAL CURRENCY), GIVEN THAT THE SERVICE IS CURRENTLY PROVIDED FREE OF CHARGE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.
12. Indemnification
You agree to indemnify and hold harmless Chrona and its founders from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising from your violation of these Terms, your User Content, or your use of the Service, including any event or meetup you organize or attend through the Service.
13. Termination
You can request deletion of your account at any time directly within the Service, from the app's account settings. Deletion requests are reviewed and fulfilled by our team and may not be instantaneous. You can also reach us at support@chronaworld.com. We may suspend or terminate your access to the Service at our discretion, with or without notice, including for violation of these Terms. Upon termination, the provisions of these Terms that by their nature should survive (including Sections 6, 10, 11, 12, and 15) will continue to apply.
14. Changes to These Terms
We may update these Terms from time to time to reflect changes to the Service or applicable law. If we make material changes, we will provide reasonable notice (such as an in-app notice or notification) before the changes take effect. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
15. Governing Law & Dispute Resolution
These Terms are governed by the laws of the Republic of Indonesia, without regard to conflict-of-laws principles, except to the extent that mandatory consumer-protection or data-protection laws of your country of residence apply and cannot be waived.
Any dispute arising out of or relating to these Terms or the Service will first be attempted to be resolved informally by contacting us at support@chronaworld.com. If a dispute cannot be resolved informally within 30 days, it will be submitted to the South Jakarta District Court (Pengadilan Negeri Jakarta Selatan), Indonesia, unless mandatory local law in your jurisdiction requires otherwise.
If you access the Service from outside Indonesia, you are responsible for compliance with local laws, and nothing in these Terms limits any non-waivable rights you may have under the mandatory law of your country of residence.
16. Miscellaneous
- Entire Agreement. These Terms, together with the Privacy Policy, constitute the entire agreement between you and Chrona regarding the Service.
- Severability. If any provision of these Terms is found unenforceable, the remaining provisions will remain in full effect.
- No Waiver. Our failure to enforce any provision is not a waiver of our right to do so later.
- Assignment. You may not assign these Terms without our consent; we may assign these Terms in connection with a merger, acquisition, or transfer of the business.
