Terms of use
Last updated 2026-10-31These terms are the agreement between you and Tóth Lóránt e.v. ("Dopler", "we", "us") for using Tavilio. They have two parts. Part 1 applies to every Dopler service. Part 2, below it on the same page, covers what is specific to Tavilio. Where Part 2 says something more specific than Part 1, Part 2 applies.
By creating an account, buying a plan or using an API key, you accept these terms. If you use a service for a company or other organisation, you accept them for that organisation and confirm you may do so.
Part 1: All Dopler services
- Registered address: 1134 Budapest, Kassák Lajos utca 67/B, Hungary
- Registration number: 52097030
- Tax number: 68682398-1-41 (EU VAT HU68682398)
- Email: support@dopler.app
The contract is concluded in English, by electronic means. It is not filed as a separate document; these terms, as published on this page with the date at the top, are the record of it, and you can save or print them at any time.
You must be at least 16 years old. To buy a paid plan you must be at least 18, or have the consent of a parent or guardian. Part 2 may set a higher age where a connected platform requires it.
Give accurate details when you sign up and keep them current. Keep your password, API keys and tokens secret; you are responsible for what happens under your account and keys, including actions taken by AI assistants or tools you connect. Revoke a key at once if you think it has leaked, and tell us if you think your account has been misused.
You may not use a Dopler service to:
- break the law, or help someone else break it;
- infringe intellectual property, privacy or other rights of others;
- send spam, malware, phishing or misleading content;
- harass, threaten or harm anyone, or publish content that sexualises minors, incites violence or is hateful;
- probe, overload or disrupt the service, get around its limits or security, or access other customers' data;
- resell or rebrand the service except where your plan allows it.
We may remove content or suspend an account that breaks these rules. Where we can, we tell you first and give you a chance to fix it. If you think we acted in error, write to us and a person will review it.
You keep all rights to the content you create, upload or publish. You give us a non-exclusive, worldwide, royalty-free licence to host, copy, process, transmit and display it only as far as needed to run the service for you, for as long as you keep it on the service. You are responsible for having the rights to your content and for what it says.
If you send us feedback or ideas, we may use them without owing you anything.
The services, their code, designs and brands belong to us or our licensors. Open-source parts are licensed under their own licences, which these terms do not limit. Apart from what those licences and your plan allow, you get no rights in our software or brands.
Plans, payment and renewal
Right of withdrawal (consumers in the EU)
- Subscriptions and other services: if you asked us to start the service during the 14 days, you pay for the part provided up to your withdrawal. Once the service has been fully provided at your express request, you cannot withdraw.
- Digital content not on a physical medium (such as downloads, licences and source code): at checkout you ask us to deliver it at once and acknowledge that you lose the right of withdrawal once delivery begins.
Availability and changes to the service
Privacy and processing terms
- act only on your documented instructions, which are these terms and how you use the service;
- keep the data confidential and limit access to the people who run the service;
- protect it with appropriate technical and organisational measures;
- use only the providers listed in the privacy policy, under contracts with the same protections, and update that list before adding one, so you can object;
- help you answer requests from the people concerned and meet your security and breach-notification duties;
- tell you without undue delay if we become aware of a breach affecting that data;
- delete or return it when the service ends, unless the law requires us to keep it;
- give you the information you need to show compliance, and allow reasonable audits.
This section is our data processing agreement under Article 28 GDPR.
Disputes and governing law
- The free plan is free, needs no card, and carries our badge on the venue's site.
- Paid plans renew automatically — monthly on the same day each month, yearly on the same date each year — until they are cancelled.
- Payment is taken by Stripe. We never hold your card details.
- Prices exclude VAT where VAT applies, which is added at checkout on the basis of the address and tax number you give.
- Cancel whenever you like, from Plan & billing in your settings. The plan runs to the end of the period you have already paid for and does not renew after that.
- We do not refund part of a period unless the law where you are says otherwise, or unless we failed to provide the service and you ask.
- If a payment fails, we will retry it and tell you. A subscription left unpaid returns the venue to the free plan, and the free plan's limits then apply — your data stays, but what exceeds the limit becomes read-only rather than being deleted.
If we change a price, we will give you at least 30 days' notice before it applies to you, and it takes effect at your next renewal. You may cancel before then.
