Draft: these Terms are not yet in effect.

ttfriday Terms of Service

These Terms are an agreement between you and the developer of ttfriday (the "App") about your use of the App. They also serve as the App's terms of use on Google Play; if you download the App from the App Store, Apple's standard Licensed Application End User License Agreement also applies. How we handle your data is described in a separate Privacy Policy: https://ttfriday.com/legal/privacy/en

If this English version and the Traditional Chinese version differ, the Traditional Chinese version prevails.

1. Who provides the App

The App is developed and operated by an individual developer, WEI KAI LIAO ("we", "us").

Contact: support@ttfriday.com. Please send any question, complaint or request about the App to this address.

The App is currently free. It has no ads and no in-app purchases (see section 8).

2. Accepting these Terms

• By downloading, installing or using the App, you confirm that you have read and agree to these Terms and the Privacy Policy. If you do not agree, please do not use the App.
• The first time you sign in and are about to create or join a shared trip, make a suggestion, record an expense or post a notice, the App will ask you to accept these Terms explicitly, and we will record which version you accepted and when. Until then you can still use the features that do not require signing in.
• You must be at least 13 years old to use the App. If you are under 18, please have your parent or legal guardian read and agree to these Terms before you use it.
• You agree to comply with any third-party terms that apply when you use the App, such as your mobile data plan and your Apple or Google account terms.

3. Your account

• You can use the App without an account. Signing in with Apple or Google is only needed to invite travel companions, join someone else's trip, or sync across phones.
• Please keep your phone and your signed-in session secure. Actions taken through your account are treated as yours, unless you can show that your account was used by someone else and you have told us.
• You can delete your account at any time in the App under "Settings" → "Delete account", or by emailing us as described at https://ttfriday.com/delete-account. What is deleted and when is set out in section 9 of the Privacy Policy.

4. User content and prohibited conduct

"User content" means what you enter in the App and share with others, including trip content, notices, suggestions, expenses and member names. You are responsible for your own user content. When using the App you must not:

• Send sexual or harassing content: post nudity, pornographic or sexually suggestive content, or use text to harass, bully, threaten or intimidate anyone, including threats to someone's physical safety.
• Harm others: post discriminatory, hateful or defamatory content aimed at a person, or disclose someone's personal data (such as a phone number, address or ID number) without their consent.
• Repost infringing material: repost text, images or trip content protected by someone else's copyright, trademark or other rights without the right holder's permission.
• Run fake-trip scams: use non-existent or deliberately misleading trips, expenses or payment details to obtain other people's money, personal data or trust.
• Scrape or automate: use scripts, bots or other automated means to access, scrape or copy content from the App or our servers in bulk, or interfere with, attack or bypass the App's security and usage limits.

In addition, the App does not offer, and must not be used for, random or anonymous chat or matching with strangers, rating or voting on real people's appearance, or primarily pornographic content. If your account is suspended, you must not evade the suspension, for example by creating another account.

5. Reporting, blocking and suspension

• Report: you can choose "Report" from the "…" menu next to every suggestion and notice written by someone else, every member in a member list, and every trip someone else has shared with you. You can also email support@ttfriday.com. The person you report is not told who reported them.
• Block: you can block a user from a member list. After that you will no longer see their suggestions, and if you are the trip's host, they are also removed from your trips.
• How we handle it: reports are reviewed by hand by the developer. When our server receives content it only checks format and length; there is no automated content moderation. If content breaks these Terms, we may remove or hide it without notice and, depending on the case, suspend or terminate the account involved. Serious or repeated violations lead directly to a permanent suspension.
• Once an account is suspended, every online feature of the App refuses requests from it, and its suggestions and notices are no longer shown to others. If you think a suspension is a mistake, email us and explain.

6. License to your content and removal

• Your user content remains yours (or its original right holder's).
• So that the App can work, you grant us a free, non-exclusive permission to store, back up, transmit and display your user content within the scope you choose to share it — that is, so members of the same trip can see it and your own phones can sync. We do not use your user content for advertising, sell it, or show it to anyone outside the trip.
• This permission ends when you delete the content, the host deletes the trip, or you delete your account. Copies already in backups are deleted as those backups expire within 30 days (Privacy Policy section 8). We cannot take back content that other members have already seen, screenshotted or copied before then.
• A host can edit or delete their own trip at any time, create a new invite link that disables the old one, and remove members; a member can leave at any time.
• We may remove content under section 5 that breaks these Terms or the law, or that a right holder lawfully asks us to remove.
• The App currently has no feature for publishing a trip to everyone. If we add one, we will first update these Terms to set out the scope of that permission and how to take content down.

7. Third-party services and AI

• Some features need to send what you enter to third parties. The only recipients are those listed in section 5 of the Privacy Policy: Amazon Web Services (including Amazon S3 and CloudFront), Sentry, Apple (Sign in with Apple only), Google (Sign in with Google only), the Claude models developed by Anthropic on Amazon Bedrock, OpenWeather, Frankfurter, Cloudflare, the email service we use for support mail, and Google as the provider of the Android text-recognition component. What each receives and why is governed by section 5 of the Privacy Policy.
• AI trip suggestions: the request text you type (up to 600 characters) is sent to Amazon Bedrock, where an AI model generates suggestions. According to AWS's public documentation, the model developer cannot access this content, and we have turned off logging of AI request content. AI suggestions may be wrong, out of date or unsuitable for you; please use your own judgement before relying on them. Do not put ID numbers, phone numbers or other personal data in the request text.
• Third-party services may be interrupted, changed or discontinued, and we cannot guarantee they will always be available.

8. Fees, purchases and refunds

• The App is currently free. There are no in-app purchases, subscriptions or ads, and we do not charge you anything.
• Mobile data charges from using the App are between you and your carrier under your plan.
• If we add paid features in the future, we will update these Terms first; payments and refunds will then be handled through the App Store or Google Play under that store's rules.

9. Information is for reference only; disclaimers

• Trip information, places and opening details, exchange rates, weather forecasts, expense splits and AI suggestions shown in the App are for reference only and may be inaccurate or delayed. Before booking, paying or setting off, rely on official or operator announcements.
• When offline, exchange rates and weather show the last values fetched, which may not be current.
• The App is provided "as is". To the extent permitted by law, we do not guarantee that the App will be uninterrupted or error-free, or that data will never be lost; please keep your own copies of important information.
• To the extent permitted by law, we are not liable for indirect damages arising from the use of, or inability to use, the App. This does not apply to damage caused by our intentional misconduct or gross negligence, or to any liability that cannot be excluded by agreement under law.
• Nothing in these Terms limits rights that the law where you live gives consumers and that cannot be waived by contract.

10. Termination

• You can stop using the App, delete your account or uninstall it at any time.
• If you break these Terms, we may suspend or terminate your account under section 5.
• We may stop offering the App or its online features. Before we do, we will give reasonable notice in the App or at https://ttfriday.com.
• Section 6 (as to content already in backups) and sections 9 and 11 survive termination of these Terms.

11. Governing law and jurisdiction

• These Terms are governed by the laws of the Republic of China (Taiwan).
• If a dispute arises over these Terms or the App, we will both first try in good faith to resolve it by email. If that fails, the Taiwan Taipei District Court has jurisdiction as the court of first instance, unless mandatory law provides otherwise (for example, a consumer's right to sue in the court where they live).
• If any provision of these Terms is held invalid, the rest remain in effect.

12. Changes to these Terms

• If these Terms change, we will update the version and effective date at the top of this page and keep every previous version available.
• Material changes (for example, new prohibited conduct, a change to the scope of the content license, or starting to charge) will be published in these Terms before they take effect, and we will notify you in the App.
• If you keep using the features that require signing in after a change takes effect, the App will ask you to accept the new version. If you do not agree, you can delete your account and keep using the features that do not require signing in.
