Privacy Policy

Who we are

Yuna is operated by Emma, an independent developer, who is the controller of the personal data described in this policy. You can reach us about privacy at [email protected].

What we collect

• Account data: email address, display name, sign-in method (password, stored only as a salted hash, or Google sign-in), language and time zone.
• Birth data: date, time and place of birth and gender for each chart you create, including charts for other people you add.
• Content: questions you ask, chat messages with Yuna, and the readings generated for you.
• Purchase data: products and plans bought, amounts, dates and the transaction reference from our payment partner. We do not receive or store full card numbers.
• Technical data: IP address, device and browser type, pages visited and error logs, used for security and reliability.
• Cookies and similar technologies, as described below.

How we use it

• To calculate your chart and generate the readings and answers you request.
• To run your account, process purchases and subscriptions, and provide support.
• To keep the Service secure, prevent abuse and fix problems.
• To improve the Service, using aggregated or de-identified information wherever possible.
• To send service emails (receipts, account notices) and, only if you opt in, occasional product news.
• To comply with legal obligations such as tax and accounting rules.

Legal bases (EEA and UK)

We process personal data to perform our contract with you (providing the Service), on the basis of our legitimate interests (security, product improvement), with your consent (optional cookies, marketing emails, which you can withdraw anytime), and to meet legal obligations.

AI processing

To generate readings and chat answers, we send the relevant birth data, chart details and your messages to third-party AI model providers acting as our processors. They process this data only to return a response to us, under contracts that restrict other uses.

We choose provider settings under which your content is not used to train their models, where such settings are available. AI output is not used to make decisions that have legal or similarly significant effects on you.

Who we share it with

• Service providers that help us run Yuna: hosting and databases, AI model providers, email delivery, customer support tools and analytics (analytics only with your consent).
• Dodo Payments and PayPal, our merchants of record for USD purchases, and Alipay, which processes CNY purchases for mainland China accounts directly with us — each under its own privacy policy.
• Authorities, where required by law or to protect rights and safety.
• A successor organisation if Yuna is merged or sold, subject to this policy.

We do not sell your personal information, and we do not share it for cross-context behavioural advertising.

International transfers

Our providers may process data outside your country. Where data leaves the EEA or UK, we rely on adequacy decisions or Standard Contractual Clauses, with additional safeguards where needed.

How long we keep it

• Account data, charts, readings and chat history: while your account is active. When you delete them, or your account, they're removed from our live systems within 30 days and from backups within 14 days.
• Charts created without an account: these stay in your browser's local storage only and are never sent to our servers, so they're removed whenever you clear your browser data, or as soon as you sign up and save them to your account.
• Purchase records: as long as tax and accounting law requires (typically 7–10 years).
• Security logs: up to 30 days.

Your rights

Depending on where you live, you have the right to access, correct, delete or export your personal data, to object to or restrict certain processing, and to withdraw consent at any time.

California residents have the right to know what we collect, to delete and correct it, and to opt out of the sale or sharing of personal information (we do neither). We won't treat you differently for exercising these rights.

You can delete charts and your account yourself in account settings. For anything else, email [email protected]. We reply within 30 days (45 days for California requests) and may need to verify your identity. You also have the right to complain to your local data protection authority.

Cookies

We use essential cookies and local storage for sign-in, security, language preference and checkout. Optional analytics and marketing cookies are off by default and are only set if you accept them in the cookie banner. You can change your choice anytime from “Cookie settings” in the footer.

Children

Yuna is not intended for anyone under 18, and we don't knowingly collect data from children. If you think a child has given us personal data, contact us and we'll delete it.

Security

We use encryption in transit, access controls and salted password hashing, and we limit staff access to personal data. No system is perfectly secure; if a breach affects you, we'll notify you as the law requires.

Changes to this policy

We'll post any changes here and update the date above. If a change is significant, we'll also let you know by email or in the Service.
