These Terms of Use (“Terms”) govern your use of the Rostra application (“Rostra”, “we”, “us”), provided by MW Supply Limited. By downloading, installing or using Rostra, you agree to these Terms. If you do not agree, do not use Rostra.
Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable licence to use Rostra on Apple devices that you own or control, as permitted by the App Store Terms of Service. You may not sell, redistribute, sublicense or rent the app, or attempt to circumvent its licensing or subscription checks.
Rostra helps solo instructors and small studios keep track of students and clients, classes, attendance, and the fees each student owes. It is an organisational and record-keeping tool. It is not accounting, tax, legal or financial advice, and its totals, balances and profitability figures are estimates based on what you enter. You are responsible for verifying any figure you rely on for invoicing, tax or business decisions.
Rostra stores your records on your device and, if you enable it, syncs them through your own private iCloud account. We do not receive or store your student and client records. Because those records describe other people, you are the controller of that information: you are responsible for having a lawful basis to record it, for keeping it accurate, and for honouring any request a student makes about their own data. Do not enter information you are not entitled to hold.
Rostra offers an auto-renewable subscription purchased through the App Store. Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your Apple Account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription at any time in your Apple Account settings. Where a free trial is offered, any unused portion is forfeited when you purchase a subscription.
Purchases are made through Apple, so refunds are handled by Apple under their policies, not by us. Request one via reportaproblem.apple.com. If something has gone wrong with the app, email us first — we would rather fix it.
You agree to use Rostra only for lawful purposes. You may not use it to harass, profile or track individuals unlawfully, and you may not attempt to reverse engineer, interfere with, or disrupt the app except to the extent that restriction is prohibited by applicable law.
See our Privacy Policy for what the app does and does not collect.
Rostra is provided “as is”, without warranties of any kind, express or implied. We do not warrant that it will be uninterrupted, error-free, or that it will preserve your data — keep your own backups. To the maximum extent permitted by law, MW Supply Limited shall not be liable for any indirect, incidental, or consequential damages, or for any loss of data, revenue or profits, arising from your use of Rostra. Our total liability shall not exceed the amount you paid for Rostra in the 12 months before the claim.
We may update Rostra and these Terms from time to time. Material changes will be posted on this page with a new “last updated” date. Continued use after changes constitutes acceptance.
