Terms of Use

Sirena Seafarer Club app and sirena.club · Effective 9 October 2026

1. The agreement

These terms are an agreement between you and Anton Dimitrov, a sole trader established in Varna, Bulgaria, who operates Sirena Seafarer Club ("the club", "the house", "we", "us"). They cover the Sirena Seafarer Club iPhone app (shown as "Sirena Club" on the Home Screen), the club's server and the website sirena.club. By signing in to the app or using it, you accept these terms and the house rules. If you do not accept them, do not use the club.

How we handle personal data is explained in the Privacy Policy, which is part of these terms. "The secretary" means the operator acting as the club's moderator.

2. Who may join, and your account

• Adults only. You must be at least 18 years old. You confirm this in the app before you take part. If we learn that an account belongs to someone under 18, we close it.
• One person, one account. You sign in with your own Apple Account using Sign in with Apple. Do not share your account, create more than one, or use someone else's.
• Be accurate. Use your real name and describe your real boat. You choose your handle once and it cannot be changed. Handles that impersonate the house or staff are not allowed.
• Keep it secure. You are responsible for what happens on your account and your iPhone. Tell us at support@sirenaclub.io if you think someone else is using it.
• Where the club is offered. The app is available only in the App Store storefronts the house chooses. It is not currently offered in the European Union storefronts.

3. Guests, members and captains

• Guests sign in for free. A guest can send and receive direct messages, read The Dock, see which rooms exist and the storm board, and join the waiting list.
• Members hold a club subscription bought in the app through the App Store, or a seat given by the house. Membership opens the rooms and Storm Rooms, asking and answering in The Dock, Nearby, the member directory, ownership verification, starting and hosting open rooms, private groups once the club has 100 members (or earlier if the house opens them), and one captain.
• Captains run a member's boat. A member invites one captain with a single-use code from the app. A captain pays nothing and is inside the club, including starting and hosting open rooms, for as long as that member's membership is active and until the member releases them. A captain who is released, or whose member leaves, keeps their own account as a guest.
• Seat numbers. A member receives the next seat number on their first paid day (or when the house gives a seat). Numbers are given in order and never reissued. A seat number stays with the account while the account exists, including while a membership has lapsed, and is retired if the account is deleted. The 1,000 seats of the first release (seats 1 to 1,000) are founding seats.
• House seats. The house may give seats, for example to staff or partners, and may end them.

4. The waiting list and invitations

• Joining. Any signed-in guest can join the waiting list and receives a place number. The app shows your place and how many people are waiting ahead of you. Members and captains do not queue, and a guest who becomes a captain leaves the list.
• Friends. Everyone on the list has a personal code and link. When a new person joins the list with your code, you move up 50 places, for up to 20 friends. A member's code starts the friend 50 places ahead instead. Each Apple Account counts once, you cannot use your own code, and a credit is taken back if the friend deletes their account within 7 days. Codes may not be bought, sold or spammed.
• Order. Invitations go out in place order, adjusted only by friend credits: first come, first served. Place numbers are never reused. If you leave the list, or let an invitation expire, you can join again at the back with a new place, because the people behind you waited too.
• Pace. Invitations go out once a day, at the daily seat drop at 8:00 New York time. Today the house sends up to 50 invitations a day, or up to 100 a day while more than twice a release's number of seats are waiting, and never more open invitations than seats left in the open release.
• Expiry. An invitation is valid for 24 hours from when it is sent. Unused invitations expire and the seat goes to the next person.
• No guarantee. Joining the list does not guarantee an invitation, a seat, a date or a price. The house may change the number of invitations per day, the invitation period, the size of releases and the pace of the club at any time, for future invitations.
• Without an invitation. The app shows the Subscribe button only to invited people. A valid club subscription you already hold, for example one restored to your Apple Account or one started with an offer code the house gave you, makes you a member even without an invitation.

5. Seat releases and prices

• Releases. Seats are offered in releases, currently of 1,000 seats each. Each release is its own auto-renewing yearly subscription product in the App Store.
• Prices start at US$99.99 a year and rise with each release. The price is always shown in the app before you buy. Today's steps, in US prices (Apple sets the local price in other storefronts), are US$99.99, US$199.99, US$249.99, US$299.99, US$349.99, US$399.99, US$449.99 and US$499.99. When a release sells out, the next release opens one step up, or two steps up if more than twice a release's number of seats are waiting at that moment. Prices never go down from one release to the next, so later releases may cost more than earlier ones. Once the last step above is reached, later releases stay at that price unless the house adds new steps, which it would announce in the app first.
• The price you pay is the price shown in the app, in your currency, before you confirm the purchase. An invitation is for a specific release, and that release's price applies for the life of the invitation.
• Renewals. Your subscription renews at the price of the product you bought, unless Apple notifies you of a price change under its rules (see section 6). A later release opening at a higher price does not change your renewal price.
• Changes. The house may change the ladder, the release size and the cadence for future releases. We never promise that a price or a seat lasts "for life".

6. The App Store subscription

7. Rooms, groups and hosting

• House rooms are run by the house: home waters, topics, seasons, The Bridge for captains, Storm Rooms and builder rooms.
• Open rooms. Any member or captain inside the club can start an open room. It is listed for everyone signed in, and any member or captain can join and talk in it; guests see the name but not the conversation. You can host up to 3 open rooms at a time and start at most one an hour (closed rooms count toward the hour). A room needs a name of 3 to 40 characters that no other open room or house room uses, a topic, and optionally a region and a description of up to 280 characters. Names and descriptions may not contain slurs or profanity.
• Private groups. Members can start invite-only groups once the club has 100 members, or earlier if the house opens them. A group has up to 100 people. You cannot start a new group while you host 5 open rooms and groups together.
• What a host can do: edit the room's name, description, topic and region; remove any message in it; remove people (someone removed from an open room cannot rejoin it; in a private group the host also adds people); and close the room, which takes it out of every list.
• What a host must do: use these tools fairly and in line with these terms and the house rules, and not use a room to sell, advertise or collect people's details. A host is a member, not staff of the club, and does not speak for the house.
• The house moderates every room. Anyone who can see a room can report it, its name or its purpose, and room reports go to the secretary along with reports on single messages. The house can remove messages, suspend accounts and close any room at any time.
• Messages in member rooms, private groups and The Bridge never leave their room: they cannot be shared to The Dock.

8. House rules

The house rules are shown in full in the app before you take part, and at any time under You, then House rules. In short:

Also: a first direct message to someone new is a request, so do not use requests to advertise or pester people, and share to The Dock only what you wrote yourself.

9. What is not allowed

• Harassment, threats, stalking, hate speech, sexual content, or content involving minors.
• Scams, fraud, phishing, or asking for money, passwords or payment details.
• Impersonating anyone, including the house, the secretary or another member, or misrepresenting your boat or your role.
• Advertising, spam, pyramid schemes, or unsolicited commercial messages.
• Sharing other people's personal data, private messages or photos without their permission.
• Content that infringes someone's copyright, trademark or other rights.
• Anything illegal, including offering illegal goods or services, or evading customs, sanctions or safety laws.
• Fake or forged documents for verification.
• Scraping, harvesting handles, automating accounts, probing or attacking the club's systems, reverse engineering the app except where the law allows it, or getting around limits, blocks or suspensions.
• Using the club to get around the App Store's payment rules, or reselling or transferring an account or a seat.

10. Reporting, blocking and moderation

• Every member, room, room message, direct message, Dock question and answer can be reported from the app. You can block anyone at any time: neither of you can send the other direct messages, you stop seeing each other in the directory and Nearby, and you stop seeing their room messages.
• The secretary reviews reports and aims to act within 24 hours. A message reported by three people is hidden until it is reviewed.
• The house may remove content, hide Dock posts, close rooms, take away a verified badge, and suspend or end an account that breaks these terms or the house rules, or puts others at risk. We may act without warning where that is needed to protect people.
• We do not watch every conversation and are not responsible for what members say. Direct messages are end-to-end encrypted, so we see a direct message only if a participant reports it.

11. Your content

You keep ownership of what you write and share. You give the club a non-exclusive, worldwide, royalty-free licence to store, copy, display and transmit your content to the people allowed to see it, as described in the Privacy Policy, only for running the club, for as long as it stays in the club. If you share a room message to The Dock, it is shown there under a name-free label. The licence ends when the content is deleted, except for copies others already received and content the law requires us to keep.

You are responsible for your content and confirm that you have the right to share it. Direct messages are end-to-end encrypted: we cannot read them and cannot recover them if you lose your iPhone.

12. Ownership verification

Members can ask for a verified owner badge by sending registration details and a photo of the registration document. A "verified owner" badge means the secretary compared the document you provided with the details you gave. It is not a guarantee of anyone's identity, character, title to a vessel, or the condition or value of a boat. Sending a forged or someone else's document ends the account. The house may refuse or remove a badge.

13. No professional, navigation or safety advice

• What members write is shared as experience, not as professional, legal, financial, insurance, technical, medical or navigation advice. You decide what to do with your boat, your crew and your money, and you should check with qualified professionals.
• Storm Rooms open on their own when a named storm reported by the US National Hurricane Center comes within 750 nautical miles of a region. They are a place to talk, not a forecast, warning or navigation service, and they may be late, incomplete or unavailable. Follow the National Hurricane Center, local authorities and your insurer's hurricane plan.
• The club is not a distress or emergency channel. Nobody monitors it for emergencies. In an emergency at sea, call on VHF channel 16, use your distress equipment, or call the Coast Guard or local emergency services.

14. Buying and selling: no brokerage

Members may list their own boats and gear where the house allows it. The club is not a yacht or ship broker or salesperson, including under Florida's Yacht and Ship Brokers' Act (chapter 326, Florida Statutes). It does not negotiate, hold deposits, act for buyers or sellers, verify listings, or take any commission or fee on a sale, and it is not a party to any deal between members. Do your own checks: survey, title, liens, documentation and the law where you buy. Professional brokers who are members must follow the house rule against selling in the rooms.

15. Events and other people's services

Events listed in the app are run by their organisers, not by the club, unless we say otherwise. Links to other websites and apps, including our separate navigation app Sirena Seafarer, are governed by their own terms. Services members offer each other are between them.

16. Copyright complaints

If you believe content in the club infringes your copyright, email support@sirenaclub.io with: your name and contact details; a description of the work; where the content is in the club (room, Dock post, handle and date); a statement that you believe in good faith the use is not authorised by the owner, its agent or the law; a statement that the information is accurate and, under penalty of perjury, that you are the owner or authorised to act for the owner; and your physical or electronic signature. We remove or disable infringing content promptly and tell the person who posted it. If your content was removed and you believe that was a mistake, you can send a counter-notice to the same address. We end the accounts of repeat infringers.

17. Suspension, termination and leaving

• You can leave at any time: in the app, go to You, then Delete account. This deletes your club account and disconnects Sign in with Apple from the club, as described in the Privacy Policy. It does not cancel an App Store subscription: cancel that in your Apple Account.
• We may suspend or end your account if you break these terms or the house rules, if the law requires it, or to protect members or the club. When we end a member's account, we tell them in the app or by email so they can turn off renewal in their Apple Account. Any refund is for Apple to decide.
• If the club closes, we will tell members in the app in advance and stop the subscriptions from renewing.
• Sections 11 (licence for content already shared), 13, 14 and 18 to 22 survive the end of these terms.

18. Disclaimers

We work to keep the club available, safe and accurate, but it is provided "as is" and "as available". To the extent the law allows, we do not promise that it will be uninterrupted, error-free or free of harmful content, that information in it is accurate or complete, or that any member is who they claim to be. This does not affect warranties and rights you have under consumer law that cannot be excluded.

19. Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential loss, loss of profits, data or goodwill, or for loss caused by what other members write or do, or by decisions you make based on information in the club, including decisions about navigation, weather, storms, purchases or sales. Our total liability for all claims about the club is limited to the greater of the amounts you paid for the membership in the 12 months before the event that caused the claim, or US$100.

Nothing in these terms limits or excludes liability for death or personal injury caused by negligence, for fraud, for intentional or grossly negligent conduct, or any other liability that cannot be limited by law, and nothing takes away rights you have as a consumer where you live.

20. Indemnity

To the extent the law allows, you agree to compensate us for reasonable losses and costs, including reasonable legal fees, arising from a third-party claim caused by your content, your breach of these terms, or your dealings with other members. This does not apply to the extent a loss was caused by us, and it does not limit your rights as a consumer.

21. Governing law and disputes

• Talk to us first. If you have a complaint, write to support@sirenaclub.io. We aim to answer within 14 days and to resolve it within 30 days.
• Law. These terms are governed by the law of Bulgaria. If you are a consumer, this choice does not take away the protection of the mandatory laws of the country or state where you live.
• Courts. Disputes go to the competent courts of Bulgaria in Varna. If you are a consumer, you may also bring a claim in the courts where you live, where the law gives you that right.
• Nothing here prevents you from contacting a consumer protection authority in your country or state.

22. Export control and sanctions

You may not use or export the app except as US law and the laws of the place where you obtained it allow. You confirm that you are not located in a country subject to a US Government embargo, or designated by the US Government as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.

23. Apple App Store terms

These terms are the end user licence agreement for the app. Because you get the app from Apple's App Store, the following also applies:

• Acknowledgement. These terms are between you and us only, not Apple. We, not Apple, are solely responsible for the app and its content.
• Licence. We grant you a limited, non-exclusive, non-transferable, revocable licence to use the app on Apple-branded devices you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. The app and the club, apart from members' content, belong to us.
• Maintenance and support. We alone provide maintenance and support for the app, at support@sirenaclub.io. Apple has no obligation to provide any maintenance or support for the app.
• Warranty. If the app fails to conform to any warranty that applies to it, you may notify Apple, and Apple will refund the purchase price of the app, if any. To the maximum extent the law allows, Apple has no other warranty obligation for the app, and any other claims, losses, liabilities, damages, costs or expenses from a failure to conform to a warranty are our responsibility, to the extent the law and these terms provide.
• Product claims. We, not Apple, are responsible for addressing any claims by you or a third party about the app or your possession or use of it, including product liability claims, claims that the app fails to meet any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
• Intellectual property. If a third party claims that the app or your possession and use of it infringes their intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.
• Legal compliance. You confirm the statements in section 22.
• Third-party terms. You must comply with applicable third-party terms when using the app, for example your mobile data agreement.
• Developer. Anton Dimitrov, sole trader, Varna, Bulgaria. Questions, complaints and claims: support@sirenaclub.io.
• Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these terms, and once you accept them, Apple has the right (and is deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

24. Changes to the club and these terms

The club will change as it grows: rooms, features, limits and the pace of invitations and releases. We may update these terms. Material changes are announced in the app before they take effect, and the new version is posted here with a new effective date. If you do not agree with a change, you can stop using the club, delete your account and cancel your subscription in your Apple Account. Changes to the price of an existing subscription happen only through Apple, as described in section 6.

If any part of these terms is found invalid, the rest stays in force. If we do not enforce a term straight away, we can still enforce it later. You may not transfer these terms or your account; we may transfer them to a new operator of the club, who must honour them, and we will tell you first.

25. Contact
