Privacy Policy
This policy explains how MixTree handles your personal information.
Last updated: September 30, 2026
Who we are
MixTree LLC (“MixTree”, “we” or “us”) operates MixTree (the “Service”) at mixtree.studio and is the controller of your personal data under the GDPR and the UK GDPR.
Information we collect
Information you give us
- Account information. We collect your name, your email address and, if you set one, your password. If you sign in with Google, we receive your name, email address and profile image from Google.
- Content. We store the songs, transitions, playlists, notes, tags and settings you add, including what you import from Rekordbox or Serato.
- Payment information. If you buy a plan, our billing providers collect your payment details, and we receive your plan and its status, your payments and whether they succeeded, and, where Clerk provides them, your card’s brand and last four digits.
- Feedback and messages. We receive what you send us by email or through the feedback widget, including any screenshot you attach, and the widget also sends the page you were on and basic device information.
Information collected automatically
- Usage data. We record the pages you open, your clicks and other interactions, session replays (recordings of what the pages showed and how you moved through them), errors in your browser, and events in the Service, your account and your subscription. Once you sign in, this is linked to your account identifier and email address.
- Device and connection data. We collect your IP address, the approximate location derived from it, your browser and device type, operating system and language, and the page that referred you.
- Advertising measurement data. TikTok receives the pages you open, events such as signups, subscriptions and payments, cookie and device identifiers, your IP address and browser information and, once you sign in, your email address and account identifier in hashed form.
- Activity records. We record when you visit the Service, how long each visit is active, and whether you use the installed app.
- How you found us. When you create an account, we record how your first visit reached us: the site or app that linked to us, the campaign tags and any ad click identifier in the link, and the page you first opened.
- Server error reports. When our code fails on our servers, we record the error and the identifier of the account it happened for.
How we use your information
We use personal information for these purposes, on the legal bases shown for people in the European Economic Area (EEA) and the UK:
| Purpose | Legal basis (EEA and UK) |
|---|---|
| Provide the Service, your account and your plan, including billing and the free plan's limits | Performance of our contract with you |
| Send messages about your account and billing, and answer your messages | Performance of our contract with you, and our legitimate interest in answering people who write to us |
| Run, secure and improve the Service, support its users and fix errors, including through activity records and our servers' error reports | Our legitimate interest in running, securing and improving the Service and supporting its users |
| Product analytics, session replays and error reports from your browser, and recording how you found us | Your consent |
| Advertising measurement with TikTok | Your consent |
| Meet legal obligations, answer lawful requests, and establish or defend legal claims | Legal obligation, and our legitimate interest in protecting our rights |
An account needs an email address and a password or a Google sign-in, and a plan needs payment details. Without them we cannot open the account or start the plan. No law requires you to give us personal information.
International data transfers
We and our providers process personal information in the United States, and some providers also process it in other countries where they run their services.
Transfers to our providers rely on their certification under the EU-US Data Privacy Framework, its UK Extension and the Swiss-US Data Privacy Framework where they hold one, and otherwise on the European Commission’s Standard Contractual Clauses and the UK Addendum in their data processing terms. You can ask us for a copy of these safeguards at mixtreesupport@gmail.com.
How long we keep information
We keep personal information while your account is open and erase it, including your analytics profile and events, when you delete your account, except as follows:
- Transitions above the free plan’s limit are deleted when an account returns to the free plan after its paid period ends.
- Clerk and Stripe keep billing records for as long as tax and accounting law requires.
- PostHog keeps analytics events and session replays, and Vercel keeps server logs, for the retention period of our plan with each.
- After an account is deleted, we keep a record of the deletion and its date, and our log of staff access to accounts, which names accounts by their identifier.
Your privacy rights
You can review and change your library and account details in the Service, and delete your account under “Delete account” in your account settings.
If you are in the EEA or the UK, you also have the right to:
- get a copy of the personal information we hold about you;
- have inaccurate information corrected;
- have your information erased;
- restrict how we use it;
- receive the information you gave us in a portable, machine-readable format;
- withdraw your consent at any time, which does not affect what we did before you withdrew it;
- complain to a data protection supervisory authority and, if you are in the UK, to us.
Right to object: you can object at any time, on grounds relating to your situation, to our use of your information based on our legitimate interests.
Do Not Track and Global Privacy Control
We do not respond to Do Not Track or Global Privacy Control signals.
TikTok, SoundCloud and Google can collect information about your activity on the Service over time and across other websites.
Automated decision-making
We do not make decisions about you by automated means alone that have legal or similarly significant effects on you.
Changes to this policy
We post changes to this policy on this page, and the “Last updated” date at the top is the date this version took effect. We tell you about material changes in the Service or by email before they apply to you.
