Terms of Service
Effective date: October 16, 2026
These terms govern your use of Rostara, a sports team management app for organizing pickup games, tracking ratings, balancing teams, and managing shared group expenses. Rostara is operated by Canvas & Core Labs LLC, a California limited liability company ("we", "us"). By creating an account or joining a group, you agree to these terms.
The service
Rostara is provided as a tool to help recreational sports groups coordinate. It is not a payment processor, banking service, or escrow service — the bookkeeping feature is a record-keeping ledger, not a money-movement system. Any actual money settlement between members happens outside Rostara.
Your account
- You are responsible for keeping your login credentials secure.
- You must be at least 18 years old to create an account.
- One account per person. Don't impersonate someone else.
- We may suspend or terminate accounts that violate these terms or are used to harm other users.
Acceptable use
While using Rostara, do not:
- Harass, threaten, or abuse other users.
- Post content that is unlawful, defamatory, or hateful.
- Use the service to send spam or unsolicited messages.
- Attempt to access another user's account, scrape data at scale, reverse-engineer the service, or interfere with its operation.
- Use Rostara to facilitate gambling, illegal payments, or any regulated financial activity.
We have no tolerance for objectionable content or abusive users. Any member can report a notice or another member, and block another member, from inside the app. We review every report within 24 hours and act on the ones that break these terms by removing the content and suspending or removing the account behind it.
Groups, roles, and content
- Owner. The user who creates a group is its owner. Owners can delete the group, regenerate invite codes, and promote or demote admins.
- Admins. Owners and admins manage the group's members, events, ratings, and bookkeeping.
- Members. Anyone who has joined a group via its invite code or claimed a profile.
- Your content. You retain ownership of content you post (notices, ledger notes, etc.) and grant Rostara a non-exclusive license to display it within your group as part of operating the service. We do not claim broader rights to your content.
- Group records. RSVPs, ratings, and ledger entries that occur within a group are part of the group's collective history. When you leave a group, the group retains that history under your former (now unclaimed) profile so the group's averages and balances stay consistent for the remaining members. See the privacy policy for details.
Ratings
Ratings exist to help admins balance teams. They are subjective opinions of individual raters, not objective claims of fact. Don't use ratings to harass or single out a member. Admins can disable ratings entirely for their group.
Paid subscriptions
- What they are. Some Rostara features are offered as an optional paid subscription, Rostara Pro. The subscription is a fee for those features only. Rostara still never holds, moves, or settles money between members.
- Where you buy it. You can subscribe in the iOS app (billed by Apple), in the Android app (billed by Google), or on the web, where the purchase is sold and processed by Link, a service of our payment partner Stripe. Each of these providers handles your payment under its own terms.
- Automatic renewal. A subscription renews automatically at the end of each billing period, at the price shown when you subscribed, until you cancel. If an offer includes a free trial, it becomes a paid subscription when the trial ends unless you cancel before then.
- Cancelling. You can cancel at any time in the subscription settings of the App Store, Google Play, or your Link account, depending on where you subscribed. Cancelling stops the next renewal, and you keep the paid features until the end of the period you have paid for. Deleting your Rostara account does not cancel a subscription, so cancel it first.
- Refunds. Apple, Google, and Link decide refund requests for purchases made through them, under their own policies. Nothing in these terms limits any refund or withdrawal right you have under the consumer protection laws where you live.
- Price changes. If we change the price, you will be told in advance, as the store you subscribed through requires, and you can cancel before the new price applies.
- If a subscription ends. If we stop offering a subscription, we will tell you in advance and stop future renewals.
Service availability
Rostara is provided "as is" and "as available." We aim for reliability but cannot guarantee the service will be uninterrupted, error-free, or that data will never be lost. We may add, change, or remove features at any time. We will give reasonable notice for material changes that affect existing users.
Disclaimer of warranties
To the maximum extent permitted by law, Rostara disclaims all warranties — express, implied, or statutory — including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that bookkeeping records, ratings, or other data are accurate, complete, or fit for any external use such as legal evidence or tax filings.
Limitation of liability
To the maximum extent permitted by law, Canvas & Core Labs LLC and its members are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profit, or goodwill arising from your use of the service. Our total liability for any claim arising from these terms or your use of Rostara will not exceed USD $50 or the amount you have paid for Rostara in the past 12 months, whichever is greater.
Termination
You can stop using Rostara at any time by leaving your groups and/or requesting account deletion. We can suspend or terminate accounts that violate these terms, with notice when possible.
Changes to these terms
We may update these terms as the service evolves. Material changes will be announced inside the app and the effective date above will be updated. Continued use of Rostara after a change constitutes acceptance of the new terms.
Disputes and governing law
If something goes wrong, please contact us first at info@rostara.app and give us 30 days to try to put it right. Most problems can be solved this way.
These terms are governed by the laws of the State of California, USA, without regard to conflict-of-laws principles. Disputes will be resolved in the state or federal courts located in San Mateo County, California, although either of us may instead bring an individual claim in a small claims court that has jurisdiction. Nothing in this section takes away a right the consumer protection laws of the country you live in give you, including the right to rely on local law or to bring a claim in your local courts.
