Terms of Use

Last updated: 6 October 2026

These Terms of Use (“Terms”) are a binding agreement between you and Bistriy Sp. z o.o. (“Bistriy”, “we”, “us”) governing your use of our applications, whether in a web browser or as a mobile app, and our websites (together, the “Services”). They apply across all of our applications. By creating an account or using a Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Services.

Applies to

These Terms cover the applications, used in a web browser or as a mobile app, and the websites operated by Bistriy Sp. z o.o. (each an “App”), all of which are intended for adults aged 18 and over:

Where an App offers astrology-based or other entertainment content (such as Synastria), it is provided for personal insight and entertainment. We do not guarantee compatibility, matches, or any particular outcome, and such content is not professional advice.

1. Who we are

The Services are operated by:

Bistriy Sp. z o.o.
ul. Królewska 65A/1, 30-081 Kraków, Poland
KRS: 0000529467
Email: support@bistriy.com

2. Eligibility

You must be at least 18 years old and able to form a binding contract to use the Services. By using our Apps you represent that you meet these requirements and that you are not barred from using the Services under applicable law.

3. Your account

You sign in with your email address via a one-time link or code. You are responsible for keeping access to your email secure and for activity that occurs through your account. Provide accurate information and keep it up to date. One person may maintain only one account per App. Notify us promptly of any unauthorised use.

4. The Apps

Each App provides its own features, which are described in the App and, where relevant, on its website. For example, Synastria calculates your natal chart from the birth data you provide and introduces you to other users whose charts it assesses as compatible, across the connection types you enable (friendship, partner, and body-doubling); its matching is based on astrological models and is offered for personal insight and entertainment. We do not perform criminal background checks or verify the identity, statements or intentions of users.

5. Subscriptions and billing

  • Subscription. Matching in Synastria requires an active auto-renewing subscription: you can create your account and your natal chart for free, and the search for compatible people starts once your subscription is active. The features included, the price and the billing period are shown in the App before you purchase.
  • Payment. In the web application, subscriptions are sold through Link, the merchant-of-record service operated by Stripe. Link charges your payment method at confirmation of purchase, collects any applicable taxes, issues receipts and handles refunds under its buyer terms, which are shown to you before you pay. If you obtained the App from an app store, payment is charged to your Apple Account or Google Play account instead.
  • Auto-renewal: a subscription automatically renews for the same period unless you cancel before the end of the current period. Cancelling stops the renewal; your subscription stays active until the period you have paid for ends. App-store subscriptions must be cancelled at least 24 hours before the period ends.
  • Manage or cancel at any time from Profile → Manage subscription in the web application, which opens Stripe’s subscription management page, or in your App Store or Google Play account settings for app-store subscriptions. Deleting the App does not cancel an app-store subscription.
  • Refunds for web purchases are handled by Link under its buyer terms and applicable law; for app-store purchases, by Apple or Google under the store’s policies. We generally cannot issue refunds directly. This does not affect your statutory consumer rights described in section 6.

6. Right of withdrawal (consumers)

If you are a consumer in the EU/EEA, you generally have the right to withdraw from a distance contract within 14 days without giving a reason. Because a subscription is a digital service supplied immediately, when you start it you expressly request that we begin providing the Service before the 14-day period ends and you acknowledge that, once the Service has been fully performed, you lose your right of withdrawal. If you withdraw after performance has begun but before it is complete, you may be required to pay for the part of the Service already provided.

Where Link, or the app store you bought from, offers its own cancellation or refund process, you may also use that. Nothing in this section limits any mandatory rights you have as a consumer, including under the Polish Consumer Rights Act (ustawa z dnia 30 maja 2014 r. o prawach konsumenta).

7. Mobile apps and app stores

Synastria is primarily offered as a web application at app.synastria.pro, which needs no installation. If we also make an App available through the Apple App Store or Google Play and you obtain it there, these Terms are between you and Bistriy only - not with Apple or Google - and the store is not responsible for the App, its content, maintenance or support. Your use of such an App must also comply with the applicable store’s terms of service. Where Apple’s Licensed Application End User License Agreement applies and conflicts with these Terms, it governs; Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Any warranty and product-liability obligations relating to such an App are ours, not Apple’s or Google’s, to the maximum extent permitted by law.

8. Acceptable use

You agree not to:

  • Harass, threaten, defraud, impersonate, or harm any person.
  • Post or send unlawful, hateful, sexually exploitative, or abusive content; content sexualising minors is strictly prohibited and will be reported.
  • Use the Services for commercial solicitation, spam, scams, or to advertise other services.
  • Use bots, scrapers, or automated means to access the Services or collect other users’ data.
  • Attempt to reverse engineer, interfere with, or compromise the security of the Services.
  • Create an account if you are a convicted sex offender, or use the Services for any illegal purpose.

9. Your content

You retain ownership of the messages and content you submit. You grant us a limited, worldwide, non-exclusive licence to host, store, transmit and display that content solely to operate and provide the Services (for example, delivering your messages to other users). You are responsible for your content and confirm you have the right to share it. We may review, moderate, or remove content and may suspend accounts that violate these Terms. You can report and block other users in the App.

We have zero tolerance for objectionable content and abusive users. Messages are screened automatically before they are delivered, and content that breaches Section 8 is rejected. In addition, any message you receive can be reported directly from the chat: reported content is removed for everyone immediately, without waiting for review, and you are offered the option to block the sender at the same time. Blocking ends the conversation for both sides. Nicknames are screened before they are saved.

We may also remove content and suspend or terminate accounts on our own initiative where we consider these Terms to have been breached. Repeated or serious breaches - in particular anything involving minors, threats, or illegal activity - will result in permanent termination and, where the law requires it, a report to the competent authorities. If you believe your account was actioned in error, contact us using the details in Section 19.

10. Safety

Your safety matters. We do not verify users and are not responsible for the conduct of any user, online or offline. In Apps that let you meet or communicate with others, use good judgement, protect your personal information, and take care when arranging to meet anyone. You interact with other users at your own risk.

11. Intellectual property

The Services, including our names, logos, designs, text and software, are owned by us or our licensors and are protected by intellectual-property laws. We grant you a personal, non-transferable, revocable licence to use the Services for their intended purpose. You may not copy, modify, distribute, or create derivative works without our permission.

12. Termination

You may stop using the Services and delete your account at any time. We may suspend or terminate your access if you violate these Terms, create risk or legal exposure, or where required by law. Sections that by their nature should survive termination (including content licence, disclaimers, liability limits, and indemnities) will survive.

13. Disclaimers

The Services are provided “as is” and “as available”. To the extent permitted by law and without limiting your mandatory rights as a consumer, we do not give warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Where an App provides astrological, compatibility or similar content (such as Synastria), it is provided for entertainment and personal insight only and is not scientific, medical, psychological, legal, financial, or relationship advice. We do not warrant that any introduction will lead to a relationship, or that the Services will be uninterrupted or error-free.

14. Limitation of liability

Nothing in these Terms excludes or limits our liability where it cannot be excluded or limited under applicable law - including liability for death or personal injury caused by our negligence, for intentional harm or gross negligence, or your mandatory rights as a consumer. Subject to that, and to the maximum extent permitted by law, Bistriy will not be liable for any indirect, incidental, special, consequential or punitive damages, or for loss of profits, data, goodwill, or for the conduct of any user. Our total liability for any claim relating to a Service is limited to the greater of the amount you paid us for that Service in the 12 months before the claim or EUR 50.

15. Indemnification

To the extent permitted by law, you agree to indemnify and hold harmless Bistriy from claims, damages and expenses (including reasonable legal fees) arising from your use of the Services, your content, or your violation of these Terms or the rights of others.

16. Complaints and dispute resolution

You can raise any complaint about the Services by emailing support@bistriy.com. We will acknowledge your complaint and respond within 14 days. If you are a consumer, you may also use out-of-court complaint and redress mechanisms; in Poland these include the permanent consumer arbitration courts (stałe polubowne sądy konsumenckie), the municipal or district consumer ombudsman (miejski/powiatowy rzecznik konsumentów), and the Office of Competition and Consumer Protection (UOKiK, uokik.gov.pl). Using these mechanisms is voluntary.

17. Changes to these Terms

We may update these Terms from time to time. We will revise the “Last updated” date above and, where appropriate, notify you in the App. Changes take effect when posted, and your continued use of the Services means you accept the updated Terms. Where a change materially reduces your rights, we will give reasonable prior notice.

18. Governing law

These Terms are governed by the laws of Poland, without regard to conflict-of-laws rules, and the competent Polish courts have jurisdiction. If you are a consumer, you also enjoy the protection of any mandatory provisions of the law of the country in which you live, and mandatory rules on which courts may hear your dispute are unaffected.
