Terms of Use

Effective 1 October 2026

These Terms of Use (the Terms) govern your use of WonderBy: the websites wonderby.com and wonderby.pl, the WonderBy mobile apps, booking links and every related service (together, the Platform). The Platform is operated by Siiware, Pl. Solny 14 lok. 3, 50-062 Wrocław, Poland, NIP 8992994343 (we, us).

Please read them carefully. Sections 7 to 11 apply only to businesses. Our Privacy Policy, Refund & Billing Policy and, for businesses, the Data Processing Agreement form part of these Terms.

1. Who we are and definitions

The Platform is provided by Siiware, Pl. Solny 14 lok. 3, 50-062 Wrocław, Poland, tax identification number (NIP) 8992994343. You can reach us at [email protected]. This address is also our single point of contact for users and for authorities under the EU Digital Services Act; we answer in English, Polish or Ukrainian.

  • Client: a person who uses the Platform to find, book or manage appointments.
  • Business: a salon, studio, independent professional or other trader that uses the Platform to offer services, manage bookings, a team or a client base.
  • Team member: a person a Business invites to the Platform, for example an employee or a contractor with their own calendar.
  • Marketplace: the public catalogue where Clients can discover Businesses.
  • Content: any text, photo, review, price, description, note or other material uploaded to the Platform.

2. Accepting these Terms and your account

By creating an account, signing in, making a booking or otherwise using the Platform you accept these Terms. If you do not agree, please do not use the Platform.

You must be at least 16 years old to create an account. If you are under the age of majority where you live, you confirm that a parent or legal guardian agrees to your use of the Platform. A Business must be run by an adult with full legal capacity, or by a company, acting for business purposes.

Your account is linked to your mobile phone number. We verify it with a one-time code sent by SMS. You must give accurate details, keep access to your phone and codes to yourself, and tell us at once if you suspect that someone else is using your account. You are responsible for activity carried out through your account unless it results from our fault. One account belongs to one person; you may not sell, share or transfer it.

You may delete your account at any time in your profile. Deletion is described in our Privacy Policy.

3. What WonderBy does and does not do

WonderBy is booking and business-management software and an online marketplace. We do not provide the beauty, wellness, grooming or other services that are booked through the Platform. Each Business alone provides its services and is solely responsible for them, including their quality and safety, qualifications, licences, hygiene, health questions and contraindications, prices, taxes, opening hours and compliance with the law.

When a Client books a service, the contract for that service is concluded directly between the Client and the Business. We are not a party to it. Consumer rights in relation to the service (for example complaints about the treatment or a refund of a deposit paid to the Business) must be exercised against the Business. We will help you contact the Business where we can.

Information about Businesses, services, prices and availability is provided by the Businesses. We moderate new Businesses before they appear on the Marketplace, but we do not guarantee that this information is complete or accurate.

4. Bookings for Clients

A booking is a request to a Business for a service at a given time. Depending on the Business's settings a booking is confirmed immediately or after the Business accepts it. The Business may reject, reschedule or cancel a booking; you will be notified in the app, by push notification or by SMS.

Please cancel bookings you cannot attend in good time. Each Business may set its own cancellation, lateness and no-show rules and may decline future bookings from a Client who repeatedly does not attend. We are not responsible for those rules or for a Business's decision to decline a booking.

The Platform sends reminders and updates about your bookings on behalf of the Business. These are service messages, not advertising.

Unless a Business expressly offers online payment, you pay the Business directly at your visit. Any payment you make to a Business is between you and that Business.

5. Reviews

Only a Client who has a booking at a Business made through the Platform can review that Business, and each review is linked to that booking. Reviews are checked by our moderators before they are published. We do not pay for reviews and do not allow Businesses to offer rewards for positive reviews. Businesses may publicly reply to reviews.

Reviews must describe your own genuine experience. You must not post reviews that are false, offensive, discriminatory, contain personal data of others, or were written by or for the Business itself or its competitors. We may refuse, remove or hide a review that breaks these Terms or the law, and we will tell the author why.

The rating shown on a Business profile is calculated from published reviews, with recent reviews weighted more heavily. If you believe a review is fake or unlawful, report it to [email protected].

6. How the Marketplace ranks Businesses

Only Businesses that have passed moderation and have an active public profile are shown on the Marketplace. By default, results are ordered by the following main parameters:

  • Distance from the location you searched or shared, when a location is given.
  • Relevance of the Business's name, category and services to your search text, when you search by text.
  • Rating score, calculated from the average rating and number of published reviews, with reviews from the last 30, 90, 180, 360 and 1,000 days weighted progressively less. Businesses without recent reviews receive a neutral score.

You can change the order, for example to sort by distance or by rating, and filter by category, location or minimum rating. Businesses cannot pay to be ranked higher. If we ever introduce paid placement, it will be clearly labelled as such.

7. Additional terms for Businesses

By creating a Business profile you confirm that you act for purposes related to your trade, business or profession and that you are authorised to bind the Business. Consumer protection rules therefore do not apply to your use of the Platform as a Business, except where mandatory law says otherwise.

You must keep your profile, services, prices, addresses and availability accurate and lawful, hold every licence or qualification your services require, and honour bookings you accept. Your profile is reviewed before it is published on the Marketplace and we may ask you for information to verify it.

Your client data. The client base you build on the Platform, including clients you import or add manually, the notes you keep about them and the messages you send to them, belongs to you. For that data you are the controller and we act as your processor under the Data Processing Agreement, which you accept together with these Terms. You are responsible for having a lawful basis to add each client, for informing clients how you use their data, and for answering their requests.

Do not record health data, data about racial or ethnic origin, religion, sexual orientation or other special categories of personal data in client notes unless you have a clear legal basis (for example explicit consent) and it is strictly necessary for the service. Never store payment card numbers, passwords or identity documents in notes.

Messages to clients. You may use the Platform to send booking confirmations, reminders and similar service messages. You may send marketing messages (such as promotional SMS campaigns) only to clients who have given you prior consent where the law requires it, including under the EU ePrivacy rules and the Polish Electronic Communications Law, and in the United States under the TCPA and CAN-SPAM. You must honour a client's request to stop receiving marketing messages without delay: mark the client as opted out in the app, and they are excluded from further campaigns. Where the law requires it, tell recipients in your message how to opt out. We forward to you any opt-out request we receive about your messages. You are responsible for the content of your messages and for complying with the law in the countries where your clients are.

You are responsible for the Team members you invite and for what they do on the Platform. Remove access promptly when someone leaves your team.

We give you access to the data your Business generates on the Platform (bookings, clients, services, reviews and statistics) through the apps. We use aggregated, anonymised data about Platform usage to operate and improve the Platform; we do not sell your client data or share it with other Businesses.

8. Plans, trials and payments for Businesses

Free plan. The Free plan is free of charge and includes one team member and up to 150 bookings per month. SMS packages are not available on the Free plan. We may change the Free plan's limits with at least 30 days' notice.

Paid plans. Paid plans are subscriptions billed monthly or annually. The price depends on your Business's country and the number of team members, and is shown before you pay. Taxes are calculated and shown at checkout.

Automatic renewal. A paid plan renews automatically at the end of each billing period for the same period and at the then-current price, and the payment method you provided is charged, until you cancel. You can cancel online at any time from your subscription settings or the billing portal; cancellation takes effect at the end of the current period and you keep access until then. Where the law requires it, you will be reminded before an annual plan renews. We will tell you at least 30 days in advance about any price increase, which you can avoid by cancelling before it takes effect.

Free trial. Where offered, a paid plan starts with a free trial (currently 7 days, once per Business) that requires a payment method. Unless you cancel before the trial ends, the subscription starts and you are charged automatically at the end of the trial.

Changes. Upgrades, such as adding team members, take effect immediately and the difference for the rest of the period is charged pro rata. Downgrades take effect at the next renewal. If a renewal payment fails, you keep access for a grace period of 72 hours while payment is retried, after which paid features are suspended until payment succeeds.

SMS packages. SMS credits are sold as one-time packages for Businesses on a paid plan. Credits are used for SMS notifications and campaigns, are tied to the Business that bought them, cannot be transferred or exchanged for cash, and are not refundable once used.

Payment processing. Payments are processed by Stripe. For purchases made through Stripe Managed Payments, Stripe (or its affiliate) acts as the reseller and merchant of record: it sells the subscription or package to you, charges your payment method, handles sales tax or VAT and issues the receipt or invoice, and Stripe's buyer terms apply to the payment. We never see or store your full card details.

Refunds are governed by our Refund & Billing Policy.

9. AI-assisted features

Some features use artificial intelligence provided by OpenAI: for example, creating a service list from a photo of your price list, suggesting service descriptions or images, or an assistant that answers messages to your Business on Instagram. Content you submit to these features is sent to our AI provider for processing, as described in our Privacy Policy.

AI output can be inaccurate or incomplete. As a Business you must review AI-generated services, prices and texts before publishing them and you remain responsible for them. Automated replies sent by the assistant are marked as coming from an AI assistant. Do not submit personal data of others to AI features unless it is necessary.

10. Acceptable use and illegal content

You must not use the Platform to:

  • break the law or infringe the rights of others, including intellectual property, privacy and personality rights;
  • offer services that are illegal, dangerous, or require a licence you do not hold;
  • post false, misleading, defamatory, hateful, violent, sexually explicit or discriminatory content;
  • send spam or marketing messages without the recipient's consent, or add people to a client base without a lawful reason;
  • make fake bookings or reviews, impersonate others or manipulate ratings;
  • scrape, copy or resell the Platform or its data, interfere with its security or operation, or reverse-engineer the apps except as permitted by law;
  • upload malware or use the Platform for fraud or money laundering.

Reporting illegal content. Anyone can report content they consider illegal or contrary to these Terms by writing to [email protected] with the exact location (link) of the content, an explanation of why it is illegal, their name and email (except for reports about child sexual abuse material), and a statement that the report is made in good faith. We confirm receipt, review reports diligently and objectively, and inform the reporter of our decision.

Our decisions. If we remove or restrict content, suspend an account or delist a Business, we tell the person affected, with a clear statement of the reasons, unless the law prevents us or the content is deceptive high-volume commercial content. You may contest any decision by replying to that notice within 6 months; a person, not an automated system, reviews it. You can also use an out-of-court dispute settlement body certified under the Digital Services Act or go to court.

We may suspend accounts that frequently post manifestly illegal content, and stop processing reports from people who frequently submit manifestly unfounded ones, after a warning.

Copyright. If you believe content infringes your copyright, send a notice to [email protected] identifying the work, the infringing material and its location, your contact details, a good-faith statement and a statement that the notice is accurate and that you are authorised to act. This process also serves as our notice procedure for users in the United States.

11. Suspension and termination

You can stop using the Platform and delete your account at any time. Cancelling a paid plan does not delete your Business; deleting your account while a paid plan is active is not possible until you cancel it.

We may restrict, suspend or terminate your access if you seriously or repeatedly breach these Terms or the law, if required by law or an authority, or to protect users or the Platform. For Businesses we will give at least 30 days' notice with the reasons before terminating the whole service, unless we must act immediately because of a legal obligation, repeated breaches, or a serious risk to users. You will then be able to export your data where the law allows.

Sections that by their nature should survive termination (such as liability, intellectual property and governing law) continue to apply.

12. Intellectual property and your content

The Platform, the WonderBy name and logo, the apps, software, design and texts are owned by us or our licensors. We grant you a personal, non-exclusive, non-transferable, revocable licence to use the Platform in line with these Terms.

You keep the rights to the Content you upload. You grant us a non-exclusive, worldwide, royalty-free licence to host, store, reproduce, adapt (for example resize images), display and distribute that Content only to operate, display and promote the Platform and your profile, for as long as the Content is on the Platform and for a reasonable time afterwards for backups and legal purposes. You confirm that you have the rights needed to grant this licence and that your Content does not infringe anyone's rights.

Mobile apps. If you download our apps from the Apple App Store or Google Play, the store's terms also apply. These Terms are between you and us, not Apple or Google, who are not responsible for the apps or their support. Apple and its subsidiaries are third-party beneficiaries of these Terms for the iOS app and may enforce them. You confirm that you are not located in a country subject to a US Government embargo and are not on any US Government list of prohibited or restricted parties.

13. Third-party services

The Platform relies on or links to services of third parties, such as Stripe for payments, Google Maps for maps, Apple and Google for app distribution, Meta for Instagram features and SMS operators. Their terms and privacy policies apply to your use of their services, and we are not responsible for them.

14. Availability, warranties and liability

We work to keep the Platform available, secure and working correctly, but we do not guarantee uninterrupted or error-free operation. We may carry out maintenance and change or discontinue features; we will give reasonable notice of material changes to paid features.

For Businesses. To the maximum extent permitted by law, the Platform is provided "as is" and "as available", and we are not liable for indirect or consequential loss, lost profits, lost revenue, lost bookings or lost data. Our total liability for all claims in any 12 months is limited to the amount you paid us in those 12 months, or 100 EUR if that is higher. You will indemnify us against claims by third parties, including your clients and Team members, resulting from your services, your Content, your messages or your breach of these Terms or the law.

For Clients who are consumers. Nothing in these Terms limits your statutory rights as a consumer, including the rights relating to digital services that do not conform to the contract. We are liable according to the law of your country of residence where it gives you more protection.

Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, for intentional misconduct or for any other liability that cannot be limited by law.

15. Complaints and technical requirements

You can submit a complaint about the Platform by email to [email protected]. Please include your phone number or email used on the Platform, a description of the problem and what you expect us to do. We will reply within 14 days. Complaints about a service provided by a Business should first be addressed to that Business.

If you are a consumer, you may also contact your local consumer protection authority or an out-of-court dispute resolution body. In Poland, consumers can get free help from the municipal (powiat) consumer ombudsman or the Trade Inspection (Inspekcja Handlowa).

To use the Platform you need an internet connection, a mobile phone number that can receive SMS, and either a current version of a common web browser (Chrome, Safari, Firefox or Edge) with JavaScript enabled or a device running a supported version of iOS or Android. Using the internet carries risks such as malware or unauthorised access; please protect your devices.

16. Changes to these Terms

We may change these Terms, for example because of new features, legal requirements or changes in our business. We will notify you at least 15 days before material changes take effect (or longer if the changes require you to adapt your business), by email, in the app or on the website. Changes that are required by law or that address an unforeseen danger may apply sooner. If you do not agree to the changes you may stop using the Platform and delete your account before they take effect; Businesses may also terminate their paid plan with effect from the change.

17. Governing law and disputes

These Terms are governed by the law of Poland, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, you also keep the protection of the mandatory rules of the country where you live.

Disputes with Businesses are decided by the competent common court in Wrocław, Poland. Consumers may bring proceedings in the courts of the country where they live, and may only be sued there.

You agree to comply with applicable export control and sanctions laws when using the Platform.

18. Final provisions and contact

If any provision of these Terms is found invalid, the rest remains in force. Our failure to enforce a provision is not a waiver of it. You may not transfer your rights under these Terms without our consent; we may transfer them to a company that takes over the Platform, in which case we will inform you.

These Terms are available in English, Polish and Ukrainian. If the versions differ, the English version prevails, unless the law of your country requires a version in your language to prevail.
