These Terms of Service (the “Terms”) are a binding agreement between you and Gokhan Kurt (“Drasyn”, “we”, “us”) governing your use of the Drasyn desktop application, websites, and cloud services (together, the “Service”). Please read them together with our Privacy Policy and Acceptable Use Policy, which are part of these Terms.
1. Agreement to these terms
By creating an account, installing the application, or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service. If you use the Service on behalf of an organisation, you confirm that you are authorised to bind that organisation to these Terms, and “you” includes that organisation.
2. Definitions
- Host — a computer running Drasyn that shares its screen or accepts a connection.
- Client — a device or browser that views or controls a Host.
- Session — a screen-sharing, remote-viewing, remote-input, or drawing connection between a Host and one or more Clients.
- Broker — our optional signaling relay that helps a Client and a Host establish a peer-to-peer connection over the internet.
- Content — files, screen data, recordings, drawings, and any other material you transmit, upload, or make available through the Service.
- Public file / Private file — the two file-service tiers described in section 7.
3. Eligibility
You must be at least 18 years old and able to form a binding contract to use the Service. You must not use the Service if you are barred from doing so under any applicable law or sanctions regime.
4. Accounts and security
- You are responsible for providing accurate account information and keeping it current.
- You are responsible for safeguarding your credentials, API keys, and connected devices, and for all activity that occurs under your account. Keep API keys secret; revoke any that may be compromised from the dashboard.
- Notify us promptly at support@drasyn.com if you suspect unauthorised use of your account.
- You may not share, sell, or transfer your account or keys to anyone else.
5. The service
Drasyn is a tool for sharing your screen, viewing and controlling computers you are authorised to access, drawing and annotating collaboratively, sharing files, and recording your own screen. Core sessions run peer-to-peer; local-network sharing involves no server of ours, and remote access uses the Broker only to help two devices connect — your screen and session data are not routed through us.
The Service is provided by an individual operator and is under active development. Features may change, and some features are experimental. We do not guarantee that the Service will be uninterrupted, error-free, or available at any particular time.
6. Remote access and control
Remote access is powerful and carries real risk, so this section is important. By using the remote-access and remote-control features you agree that:
- You will only connect to, view, or control computers that you own or that you are clearly authorised to access.
- Where a Session involves another person’s screen, device, or activity, you are responsible for obtaining any consent required by law before viewing, controlling, or recording it.
- You will not use the Service for unauthorised access, covert surveillance, stalking, technical-support or refund scams, impersonation, or to induce anyone to grant you access under false pretences.
- We provide the connection technology only. We do not supervise Sessions, cannot see their content, and are not a party to what happens during them. You are solely responsible for your conduct and its consequences during a Session.
7. Your content and files
You retain all ownership of your Content. You grant us only the limited licence necessary to operate the Service — for example, to store, transmit, and serve the files you upload, and to make Public files available at their URLs. This licence ends when the Content is deleted, except for content already distributed via capability links and for backups or logs pending routine deletion.
You are responsible for your Content and for having the rights to use and share it. The file service has two tiers:
- Public files are served from a stable, unguessable URL. Anyone who has the URL can access the file; such links may be cached or embedded elsewhere. Deleting a Public file removes it after a short grace period.
- Private files are encrypted on your device before upload and shared through a revocable capability link. We cannot read them and cannot recover them if you lose the key. Private files expire after their retention period.
You must not upload or share Content that violates our Acceptable Use Policy.
8. Moderation and takedown
We may, but are not obliged to, review Public files with an automated content-safety check. We may remove, disable, or restrict access to Content, and suspend or terminate accounts, where we reasonably believe there is a violation of these Terms or the law, or a risk to others. Public URLs for removed Content may return an unavailable-for-legal-reasons response rather than simply disappearing.
If you believe Content infringes your rights or is otherwise unlawful, report it to support@drasyn.com with enough detail to identify the Content and the basis of your complaint. We respond to valid notices, including copyright and KVKK/data-protection complaints.
9. Acceptable use
Your use of the Service is subject to our Acceptable Use Policy, which prohibits, among other things, illegal content, malware, infringement, unauthorised access, abuse of others, and misuse of our infrastructure. Violations may result in suspension or termination.
10. Plans, billing, and refunds
- Plans. The Service offers a free tier and one or more paid tiers, each with its own storage quota and limits. The current plan details are shown in the dashboard.
- Payment processor. Paid subscriptions are processed by Polar, acting as our merchant of record. Your purchase is also subject to Polar’s terms, and Polar handles payment, invoicing, and applicable taxes. We do not receive or store your card details.
- Renewal. Subscriptions renew automatically for successive periods until you cancel. You can cancel or manage your subscription at any time through the customer portal; cancellation takes effect at the end of the current billing period.
- Refunds and withdrawal. Except where required by law, fees are non-refundable and there are no refunds for partial periods. If you are a consumer, your mandatory statutory rights — including any right of withdrawal under Turkish consumer protection law or the equivalent in your jurisdiction — are unaffected by this section.
- Price changes. We may change prices or plan features. We will give reasonable advance notice of changes affecting a paid plan, and changes take effect on your next renewal.
- Downgrades. If you downgrade or cancel and your stored data exceeds the lower tier’s quota, you may need to remove data; we may prevent new uploads until you are within quota.
11. Third-party services
The Service relies on third parties (including Cloudflare, Polar, Resend, and, if you use them, GitHub or Google sign-in, and public STUN servers). Your use of those services through Drasyn may be subject to their terms, and we are not responsible for third-party services or their availability.
12. Intellectual property
The Service, including the Drasyn name and logo, is protected by intellectual-property rights and belongs to us or our licensors. We grant you a limited, non-exclusive, non-transferable, revocable licence to use the Service in accordance with these Terms. Open-source components included in the Service remain governed by their own licences. You may not copy, modify, reverse-engineer (except as permitted by law), resell, or create derivative works of the Service except as expressly allowed.
13. Suspension and termination
You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you breach these Terms or the Acceptable Use Policy, if required by law, or to protect the Service or others. On termination, your right to use the Service ends and your data is handled as described in the Privacy Policy. Sections that by their nature should survive termination (e.g. content licences already granted, disclaimers, liability limits, indemnities, and governing law) will survive.
14. Disclaimers
To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, title, or non-infringement. We do not warrant that the Service will be uninterrupted, secure, or free of errors, that connections will always succeed, or that stored data will never be lost. You are responsible for keeping your own backups of important data and recordings.
15. Limitation of liability
To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, goodwill, or business, arising out of or relating to the Service — including anything that happens during a Session, unauthorised access to your devices by a third party, or loss of Content.
To the fullest extent permitted by law, our total aggregate liability for all claims relating to the Service is limited to the greater of (a) the amount you paid us for the Service in the twelve months before the event giving rise to the claim, or (b) fifty euros (€50). Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including your mandatory consumer rights.
16. Indemnification
You agree to indemnify and hold us harmless from claims, damages, and expenses (including reasonable legal fees) arising from your Content, your use of the Service, your violation of these Terms or the Acceptable Use Policy, or your infringement of any third-party right — including any claim arising from your use of the remote-access features.
17. Changes
We may modify the Service and these Terms. When we make material changes to the Terms, we will update the “Last updated” date and, where appropriate, provide notice. Continued use of the Service after changes take effect constitutes acceptance. If you do not agree to the updated Terms, stop using the Service.
18. Governing law and disputes
These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-laws rules. Subject to the mandatory rights below, the courts of the courts and enforcement offices of [CITY], Türkiye have exclusive jurisdiction over any dispute arising out of or relating to the Service. If you are a consumer, this does not deprive you of the protection of mandatory provisions of the law of your place of residence, and you may also bring proceedings before the consumer arbitration committees or consumer courts available to you under applicable consumer protection law.
19. General
- Entire agreement. These Terms, with the Privacy Policy and Acceptable Use Policy, are the entire agreement between you and us regarding the Service.
- Severability. If any provision is held unenforceable, the rest remains in effect.
- No waiver. Our failure to enforce a provision is not a waiver of it.
- Assignment. You may not assign these Terms without our consent; we may assign them in connection with a transfer of the Service.
- Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.
- Notices. We may give notice through the Service or by email; you can reach us at support@drasyn.com.
