We keep your birth details and your answers. Never who you are.
- We keep the birth date, time and place you enter, the area you chose and your True / Not me answers. We use them to make readings more accurate. We never ask for your name, and nothing we keep with them identifies you.
- There is no account and no advertising. We use Google Analytics, which sets a cookie, to count visits and see which pages and tools people use. In the UK, the EU and Switzerland it counts you only if you say yes.
- When you open a reading in full, we keep the finished reading so your private link keeps working. It is kept apart from the birth records, with nothing that links the two.
- If you ask a free calculator for its full report, we email it to you. We keep your email address, which calculator it was and the date, so we know who has had one. We never keep your birth details for this, and it does not sign you up for anything.
- If you ask for the weekly note, we keep your email address for that and nothing else. It is never linked to a reading, and every note has a one-click unsubscribe.
- We never sell or share your information for marketing.

What do we collect, and why?
When you use the free reading
You enter a date, a time, a place and how sure you are of the time. We use them to work out your chart and your reading. We keep them, along with:
- the area you chose
- each statement we showed you, and your True / Not me answer
- how far you went (to the result, or on to the full reading)
- the kind of place you came from, such as a search engine, Instagram, our app in ChatGPT or Claude, or another page of this site, so we know which of them lead to readings
We keep no name, email, phone number, IP address or device details with this record. We use it only to study which readings ring true for which charts, and to make them more accurate.
When you open a reading in full
We put your reading together at the moment you choose to open it in full, and we keep that finished reading. It holds the planets named, the reasons, what you marked, what the reading says for you, and the kind of place you came from. It is stored separately from the birth records above, and nothing in our data connects the two.
When you ask a calculator for its full report
The free calculators show a short answer on the page, and the full report comes by email. You give an email address. We work out the report from the birth details you entered and send it to you once. We keep the address, which calculator it was and the date, so we know who has had a report. We don’t keep the birth details or the report itself.
To stop anyone using the form to flood someone’s inbox, we also keep a scrambled (hashed) copy of the address and of your IP address for one day. The address is not added to the weekly note unless you tick that box and confirm it.
When you ask for the weekly note
You give an email address, and nothing else. We send one message to check it is you, and we add you to the list only when you tap the link in it. We keep the address, the date you confirmed and the page you signed up on. These are stored apart from readings and birth records, and nothing connects them.
Every note has a one-click unsubscribe link. After you unsubscribe, we keep the address only so that we never email you again. We delete it if you ask.
When you use our app in ChatGPT or Claude
The assistant sends us only what the question needs: a birth date, a birth time if you gave one, and a town. We use them to work out the answer and send it back. We don’t keep them. We never receive your name, your email or the rest of your conversation.
We count how many questions each tool answers each day, and in which assistant. The count holds nothing about you or your question. OpenAI and Anthropic handle your conversation under their own privacy policies.
When you visit the site
We use Google Analytics to count visits: which pages are read, which tools are used, roughly where in the world visitors are, and how they found us, such as a search engine, Instagram or an AI assistant. It sets a cookie so it can tell one visit from the next. It also notes a few moments by name only: a calculator giving its answer, a step of the reading, a report emailed, a sign-up to the weekly note.
It never receives your birth details, your answers, your email address or your private reading link. Its advertising features are switched off.
In the UK, the EU and Switzerland we ask first, with one short question at the bottom of the page, and it counts you only if you say yes. Wherever you are, you can change this for your own device: . Your choice is kept on your device, and it starts from the next page you open.
Your private link
Your reading lives at a private address that only you are given. We store only a scrambled (hashed) copy of that address, so our database alone cannot open your reading. Anyone who has the link can view the page, so share it only if you want to.
Who else is involved?
- Resend sends our emails: the confirmation, the weekly note and the calculator reports you ask for. Nothing else. It receives your email address and the message so it can deliver it.
- Cloudflare hosts the site and runs the server that works out readings. Like any host, it processes technical information such as your IP address, to deliver pages and keep the site secure.
- Google Analytics counts visits for us, as described above. Google receives your IP address and the pages you visit, and handles them under its own privacy policy. We don’t use it for advertising.
- Google Fonts supplies some of the typefaces. Your browser asks Google for the font files, so Google receives your IP address when it does.
How long do we keep things?
- Birth details, the area and your answers: kept for up to five years to improve readings, then deleted.
- A calculator report’s record (your address, the calculator, the date): kept until you ask us to delete it.
- A weekly-note address: kept until you unsubscribe. After that, it is kept only as a record that we must not email you again, until you ask us to delete it.
- A reading you opened: kept so your private link keeps working, until you ask us to delete it.
- Google Analytics: Google keeps the detailed visit records for two months. The totals in its reports stay longer.
What can you ask us to do?
- Delete your reading. Send its private link to [email protected], at any time. Once it is deleted, the link stops working.
- See or correct what we hold. You can ask what we hold about you, or ask us to correct it.
- Remove a birth record. The birth records hold no name or contact details, so we cannot find one by who you are. Tell us the birth date, time and place you entered, and we will delete every record that matches.
- Delete your calculator report record. Write to [email protected] from that address.
- Leave the weekly note. Use the unsubscribe link in any email. To have the address deleted as well, write to [email protected] from it.
