Terms of service
Last updated: 1 January 2026
These terms govern the relationship between Silryu Lda. and clubs that use the platform. By creating an account, you agree to be bound by them. If you do not agree, do not create an account.
What Silryu is
Silryu is a SaaS that lets martial arts clubs manage athletes, attendance, lesson plans, billing and parent communications. Plans (Starter, Growth, Pro and Enterprise) are detailed on the pricing page. We may add or remove features over time and will notify you of material changes 30 days in advance.
Your account
You must be at least 18 to create an account. The data you give us must be accurate. You are responsible for keeping your password safe and for the actions of every user you invite. Two-factor authentication is mandatory for all staff accounts.
Billing
Plans are billed monthly or annually in euros, with EU VAT added on the invoice. Payments are processed by Stripe and PayPal; we do not store card details. Failed payments are retried following the dunning rules in the dashboard. After 21 days of unsuccessful retries the account is suspended. Annual plans cannot be refunded mid-cycle but can be cancelled to prevent renewal.
Cancellation
You can cancel any time from the dashboard. Cancellation takes effect at the end of your current billing cycle. After cancellation your account moves to read-only for 30 days so you can export your data; after that the database entries are purged in line with our privacy notice.
Suspension and termination
We may suspend or terminate accounts in case of unpaid invoices, abusive use of the AI planner (e.g. generating non-training content), violation of GDPR by the controller (e.g. uploading athlete data without parental consent for minors), or breach of these terms. Material breaches give you 30 days to fix the issue before suspension.
Limits of liability
Silryu is provided as is. We are liable up to the amount you paid us in the last 12 months. We are not liable for loss of profit, indirect damages or third-party actions. Nothing in these terms limits liability that cannot be limited under EU law (e.g. gross negligence, consumer rights).
Governing law
These terms are governed by Portuguese law. Disputes go to the courts of Lisbon, except where mandatory consumer protection law of your residence applies. EU customers can also use the European online dispute resolution platform.
