Privacy
Last updated: 9 October 2026
Your birth details are personal data. This page explains, in plain terms, exactly what happens to them. It describes what the software actually does, it is written from the code, not adapted from a template.
The short version
You type your birth date, time and place. They are sent to our server, which calculates your chart and sends it straight back to your browser. By default we do not store them, there are no analytics and no tracking of any kind, and when you close the tab the chart is gone.
There is now one exception, and it is entirely your choice: if you create an account and save a person to your cabinet, the birth details you save arestored in a database so you don't have to type them again. That only happens if you sign up and save, it is covered in full under Accounts below, and you can delete any saved person at any time. If you never create an account, nothing about the paragraph above changes.
There are two more things you can choose to do, and each stores one extra thing. If you ask for the free reading by email, we keep your email address. If you buy a PDF report from our shop, we keep your email address and what you bought. In both cases your birth details are still used once to make the PDF and are not stored, but the PDF itself, which shows your name and birth details, is sent to your inbox as an email attachment. Both are set out in full under Email and orders below.
Two things leave our server. The place nameyou type goes to a mapping service to turn “Manchester” into coordinates, never your date or time of birth. And if you ask for the written reading, your computed chart is sent to an AI provider to be interpreted into prose. That second one is new, it is the most significant thing on this page, and it is set out in full under Artificial intelligence below.
Who is responsible for your data
Christos Mavridis, trading as CM Solutions, of 1 Lowick Ct, Newcastle upon Tyne, NE3 1YQ, United Kingdom. Contact: hello@psychart.app. An ICO registration is not yet in place.
What we collect
| What | Why | Kept? |
|---|---|---|
| Date of birth | Positions of the Sun, Moon and planets on that day | No |
| Time of birth (optional) | The Ascendant and house cusps. Without it we tell you what can't be determined rather than guess | No |
| Place of birth | Coordinates, which give the correct historical timezone and the angles of the chart | No |
| Your name (optional) | Only to address the reading. It has no effect whatsoever on the calculation | No |
| Email address (free reading) | To send you the reading you asked for, and to find your record if you write to us | Yes, until you ask us to delete it |
| Email address and order details (paid reports) | To email you a link to enter your birth details, to send the PDF, to deal with a problem with your order, and to keep the sales records the law requires | Yes, for as long as UK law requires us to keep sales records |
The Kept? column above is the default. If you create an account and save a person, the details you save are kept until you delete them, see Accounts.
Our hosting provider also records ordinary technical information for every request, your IP address, the time, and your browser's user-agent string. This is standard server logging, used to keep the service running and to investigate faults. We do not combine it with your birth details.
If a calculation fails, the error message is written to our server logs so we can fix it. Those messages can include the specific value that caused the failure, for example, an out-of-range year. They do not contain your full birth details or your name.
Our lawful basis
For your birth details: performance of a contract (UK GDPR Article 6(1)(b)). You give them to us for one purpose, to get the chart you asked for, and we use them for nothing else. For server logs: legitimate interests (Article 6(1)(f)), namely keeping the service available and secure. For anything you save to an account, the basis is your consent (Article 6(1)(a)), see Accounts.
Your chart is not used to make any automated decision that produces legal effects or similarly significantly affects you. It is a reflective tool, not a decision about you.
How long we keep things
Your birth details: not at all. They exist in server memory for the fraction of a second it takes to compute your chart, and are gone when the response is sent. There is nothing to delete, because there is nothing stored.
Server logs are retained by our hosting provider for a short period under their standard retention, then discarded.
What we keep is data you deliberately save to an account, which stays until you delete it (see Accounts), the email address you gave for the free reading, which stays until you ask us to delete it, and the record of a paid order, which stays for as long as UK law requires us to keep sales records (see Email and orders).
Email and orders
The free reading. You give an email address and your birth details. We make a short PDF from the birth details and email it to that address. We keep the email address, whether you ticked the separate, optional box to hear about new reports, and which form you used. We do not keep the birth details. Sending you the reading is the service you asked for. We only send you anything else if you ticked that box, and every such email can be answered with a request to stop, which we act on.
Buying a report. You pay in our shop, which is run by Shopify. Shopify handles your payment and card details; they never reach us. Shopify tells us that an order was paid, and we keep your email address, the reports you bought and a private link for that order. We email you the link. You open it, enter the birth details the report should be made for, and we email the PDF to the address on your order. We do not keep the birth details. We do keep the time you confirmed you wanted the PDF made now, because the law asks us to be able to show it. The shop sets the cookies Shopify needs for a cart and checkout; our own pages set none.
A dream interpretation. When you write a dream on our dream page, we save what you wrote (the dream, and how you felt and what is going on in life if you added them) with a private link, before you pay, so it survives the trip through checkout. When Shopify tells us the order was paid, we keep your email address and the order with it, send the dream to the AI providers below to be read and painted, and keep the interpretation and the cover so you can read them again from your link. Anyone with that link can read the dream, so keep it to yourself unless you want to share it. A dream that is never paid for is deleted after 7 days; everything else is deleted after a year, or sooner if you ask us by replying to your order email.
A written tarot reading. Drawing cards is free and stores nothing: your question stays in your browser. If you ask for a written reading of a spread, we save the spread you drew (which spread, and the number the shuffle came from, so we can lay the same cards again) and your question, if you gave one, with a private link, before you pay. When Shopify tells us the order was paid, we keep your email address and the order with it, send the cards and your question to the AI provider below to be read, and keep the reading so you can open it again from your link. Anyone with that link can read your question, so keep it to yourself unless you want to share it. A reading that is never paid for is deleted after 7 days; everything else is deleted after a year, or sooner if you ask us by replying to your order email.
The PDF is personal. It shows your name and birth details, and it travels as an email attachment through our email provider, Resend, and then through your own email provider. Anyone with access to that inbox can read it.
Lawful basis. For the reading and the PDF: performance of a contract (Article 6(1)(b)). For the sales records: legal obligation (Article 6(1)(c)). For any marketing email: your consent (Article 6(1)(a)), which you can withdraw at any time.
Deleting it. Email us at hello@psychart.app and we will remove your email address from the list. We cannot delete the record of a paid order before the law allows, but we will remove everything else that identifies you.
Accounts (optional)
Everything above describes the default, no-account experience. If you create an account, two things change, and only these two.
We store the people you save.When you save someone to your cabinet, the details you save (the name you give them, their date, time and place of birth, and the coordinates and country of that place) are kept in a database so any tool can run for them without you typing it all again. They stay until you delete them. Each saved person is visible only to you: the database enforces, at the level of each individual row, that one account can never read another's data.
We store your sign-in. To sign in you give an email address and a password. The password is never kept in readable form, our authentication provider stores only a secure one-way hash of it. While you are signed in, a single session cookie keeps you signed in between pages. It is strictly necessary for the account to work and is never used for tracking.
The lawful basis is your consent (UK GDPR Article 6(1)(a)). An account is an optional convenience you opt into, and you can withdraw at any time by deleting the data or closing the account.
Deleting it. You can delete any saved person from your cabinet at any moment, and it is removed straight away. To close your account entirely and erase everything, email us at hello@psychart.app and we will do it.
The account database is provided by Supabase, hosted in the EU (Ireland). Your saved details live only there. Running a tool for a saved person computes a chart from those details exactly as if you had typed them, so everything above still applies, in particular, if you then ask for a written reading, it is the computed chart that goes to the AI provider, never the saved details themselves.
Who else is involved
These other companies touch part of this:
| Who | What they receive | Where |
|---|---|---|
| Vercel Inc., hosting | The request itself, including your birth details in transit, plus your IP address. They process it to run the server; it is not stored afterwards. | USA / global |
| Open-Meteo, place lookup | Only the place name you type. Not your date of birth, not your time of birth, not your name. | Germany / EU |
| Anthropic, the written reading, reached through Vercel's AI Gateway | Your computed chart, the positions, signs, houses and aspects worked out from your birth details, and your first name if you gave one. Not your raw date, time or place of birth: by that point they have already been turned into a chart. Only sent when you ask for a reading. | USA |
| Anthropic and Black Forest Labs, the dream interpretation and its cover, and the written tarot reading, reached through Vercel's AI Gateway | The dream you wrote, and how you felt and what is going on in life if you added them (Anthropic), and a short description of one scene from it (Black Forest Labs, which paints the cover). For a tarot reading, the cards you drew and your question (Anthropic). Not your name or email. Only after you have paid for an interpretation or a reading. | USA / Germany |
| Supabase, the database | If you create an account: your email, a hash of your password, and the birth details of the people you save. If you ask for the free reading or buy a report: your email address and, for an order, what you bought. Never your birth details unless you save them to an account. If you write a dream: the dream, the interpretation and its cover, and your email once you have paid. If you ask for a written tarot reading: the spread you drew, your question, the reading, and your email once you have paid. | EU / Ireland |
| Resend, email delivery | Your email address and the PDF we send you, which shows your name and birth details. Only when you ask for the free reading or buy a report. | USA |
| Shopify, the shop and payments | What you give the shop at checkout: your email, billing details and payment details. We never see your card. Shopify tells us your email and what you bought. | Canada / USA / EU |
Because Vercel, Resend and Shopify are not UK companies, your data may be processed outside the UK. Those transfers rely on the UK International Data Transfer Addendum to the EU Standard Contractual Clauses or an equivalent safeguard.
Artificial intelligence
If you ask for the written reading, your computed chart is sent to an AI provider. That provider is Anthropic, reached through Vercel's AI Gateway. It receives the chart, your placements, houses and aspects, plus your first name if you gave one, and writes the interpretation you read. It does not receive your raw date, time or place of birth; those have already been turned into a chart before anything is sent.
The chart itself is arithmetic, and no language model touches it. Every position is calculated in code and handed to the model as a finished fact. The model may only interpret what it is given, it is never asked where a planet was, because a model asked for a number will invent one.
This only happens when you ask for a reading. Generating the chart alone contacts no AI provider at all.
We got this wrong once, and it is fair that you know. This page previously said nothing was sent to an AI provider, and promised we would update it before the reading went live. The reading shipped first and this page was inaccurate for a short period on 15 July 2026, until it was noticed and corrected. Nobody was misled deliberately, and no birth details were stored at any point, but the promise was to tell you first, and we did not.
Cookies and tracking
If you are not signed in, there are none: no cookies, no local storage, no analytics, no advertising pixels, no session recording, no third-party scripts of any kind. If you sign in, a single strictly-necessary session cookie keeps you signed in, and nothing more. There are still no analytics, no advertising and no trackers of any kind, signed in or not. This isn't a privacy posture we're claiming, it's simply what the code does, and you can verify it in your browser's network tab.
Your rights
Under UK GDPR you have the right to access, correct, erase, restrict, object to, and port your personal data. If you have never created an account, most of these have nothing to act on, because we hold nothing: no record and no profile of you. If you do have an account, they apply to the details you saved: you can see and delete any of them from your cabinet yourself at any time, and for anything else, email us at hello@psychart.app.
If you are unhappy with how your data has been handled you can complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113. We'd rather you told us first, but you do not have to.
