Terms of Service

1. About these Terms

Calçada is a free tile-drafting strategy game. These Terms of Service (the "Terms") are an agreement between you and Ankur Goyal, trading as "One Point Zero" ("we", "us", "the developer"), who makes and operates Calçada (the "App"), available as an Android app and on the web.

We have tried to keep these Terms short and in plain English. Please read them. They explain what you can expect from us and what we ask of you in return.

2. Accepting these Terms

By creating an account, signing in, or otherwise using the App, you agree to these Terms. If you do not agree, please do not use the App.

Calçada is a strategy game made for a general board-game audience. The App is not designed for or directed at children, and it does not knowingly collect information from them. You must be at least 13 years old to use the App — or older, if the age of digital consent where you live is higher than 13, in which case you must meet that age. If you are below that age, please do not use the App.

3. Your licence to use the App

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use the App for your own private, non-commercial enjoyment. That is it — play the game, have fun.

This licence does not let you sell, rent, sub-licence, or commercially exploit the App; copy, modify, decompile, or reverse-engineer it (except where the law expressly allows); strip out or alter our names, logos, or notices; or use the App to build a competing product. The App, its code, art, the Calçada name and branding, and all related intellectual property remain ours or our licensors'. All rights reserved.

4. The App is free

Calçada is free to play. In this version there are no in-app purchases, no subscriptions, no paid upgrades, and no advertising. We will never ask you to pay to play the core game.

If we ever introduce optional paid features in a future version, we will make that clear in the App and update these Terms beforehand. You will not be charged for anything without being told first.

Standard mobile-data charges from your network provider may apply when you play online. When you download the Android app from Google Play, Google Play's own terms also apply.

5. Your account

To play online and use the friends and stats features, you sign in with either a one-time email code or your Google account. We do not use passwords for player accounts. When you sign in, your email is held by our authentication provider (Supabase) to identify your account; it is not shown to other players or stored in your public game profile.

You are responsible for keeping access to your sign-in email or Google account secure, since anyone who controls those can sign in as you. Please let us know if you think someone else has accessed your account. You are responsible for activity that happens under your account.

6. Usernames, display names, and what is public

You choose a username (a handle, 3–20 characters) and a display name (1–30 characters). These are visible to other players: they appear to your opponents, in match results, and in the friends feature, and they can be looked up by other signed-in players. Treat your username and display name as public.

When you choose or change them, you agree they will not: be offensive, hateful, harassing, obscene, or threatening; impersonate another person, the developer, or any brand; infringe anyone's trademark or other rights; or contain spam, advertising, or contact details. You are responsible for the names you pick, and you grant us permission to display them within the App as part of normal gameplay. We may change or reset a name that breaks these rules.

7. Fair play and acceptable conduct

Calçada is meant to be a fair, calm game. When you use it, please do not:

• cheat, or use modified clients, scripts, bots, macros, or automation to play matches on your behalf;
• exploit bugs, glitches, or unintended behaviour instead of reporting them;
• tamper with, intercept, or forge game state, scores, or network messages, or otherwise try to gain an unfair advantage in multiplayer;
• disrupt, stall, or abuse other players, opponents, or matchmaking (for example, deliberately abandoning matches to spoil others' games);
• attempt to overload, attack, probe, or gain unauthorised access to the App, its servers, or other players' accounts; or
• use the App for anything illegal.

A note on opponents: Calçada includes computer-controlled opponents. To keep matchmaking quick when a human opponent is not immediately available, you may at times be matched with one. The fair-play rules above apply to every match.

8. Your content

The main content you provide is your username and display name (covered in section 6). You keep ownership of what you choose, and you are responsible for making sure it does not break these Terms or anyone else's rights. You give us a limited permission to store and display that content as needed to run the game — for example, showing your name to opponents and in match history. We may remove or change content that breaks these Terms.

9. Availability — the App is provided "as is"

We are a small, independent developer, and we offer Calçada free of charge. The App is provided "as is" and "as available", without warranties of any kind, whether express or implied — including any implied warranties of merchantability, fitness for a particular purpose, or non-infringement — to the fullest extent the law allows.

We do not promise the App will always be available, uninterrupted, error-free, or secure, that matches will never be interrupted by connection problems, or that it will work perfectly on every device. We may add, change, suspend, or discontinue features, including online multiplayer, at any time. Nothing in these Terms removes any legal rights you have as a consumer that cannot be excluded under the law where you live.

10. Limitation of liability

To the extent permitted by law, we are not liable for indirect, incidental, special, or consequential losses, or for lost data, lost progress, or lost opportunity, arising from your use of (or inability to use) the App. Because Calçada is provided to you free of charge, our total liability to you for any claim relating to the App is limited to the amount you paid to use it — which is zero.

We are not limiting or excluding liability for anything that cannot lawfully be limited or excluded, such as liability for death or personal injury caused by our negligence, for fraud, or for any consumer rights that the law protects regardless of these Terms.

11. Suspending or ending access

You can stop using Calçada at any time. You can delete your account and associated data yourself in Settings → Account → Delete account, or by contacting us (section 15).

On account deletion we remove or anonymise your profile and personal data; anonymised or aggregate match records, and a name already shown to past opponents in their own game history, may be retained. See the Privacy Policy for detail.

We may suspend, limit, or terminate your access to the App — including your account — if you break these Terms, particularly the fair-play and acceptable-conduct rules, or if we reasonably need to in order to protect other players, the service, or the developer. Where it is reasonable and appropriate, we will aim to give you notice and a chance to put things right, but for serious or repeated abuse we may act immediately. If we end your access, the licence in section 3 ends too.

12. Changes to these Terms

We may update these Terms from time to time — for example, when we add features or when the law changes. If we make a significant change, we will update the effective date and make the new version available in the App or on the website before it takes effect. If you keep using the App after a change takes effect, that means you accept the updated Terms. If you do not agree to a change, please stop using the App.

13. Governing law

These Terms are governed by the laws of India, without regard to conflict-of-laws rules, and the courts of India will have jurisdiction over any dispute — except where mandatory local consumer-protection law gives you the right to bring a claim in, or rely on the laws of, the country where you live.

14. General

If any part of these Terms is found to be unenforceable, the rest stays in full force. If we do not enforce a provision, that is not a waiver of it. These Terms are the whole agreement between you and us about the App.

15. Contact

Questions about these Terms, reports of abuse or fair-play problems, or account-deletion requests can be sent to hi@calcada.app. A separate Privacy Policy explains how we handle your data.
