Your birth data, plainly handled

To compute a chart: your date, time and place of birth, your gender (an input to the traditional formulas), and optionally your name and a question on your mind. An email address is required to start a reading and retrieve it later. If you buy the full report and answer its optional interview — what you do, what you are working towards, family, relationship, the city you live in, what you enjoy outside work — those answers are kept on your account too; every one of them is optional, you can see, rebuild or remove them on the account page, and they are used only to write the "for you" lines in your own report. Separately, we use Google Analytics and Google Ads to measure visits, sign-ups, completed readings, checkouts and purchases. We estimate your country from your IP address using a locally hosted DB-IP database; this feature does not store your IP or send it to DB-IP. The estimate can be wrong, particularly when using a VPN. In Malaysia, Singapore and Australia, visit and advertising measurement is on unless you switch it off: Google sets analytics and advertising cookies, our pages keep the advertising click reference they arrived with (in this browser, for up to 90 days), and when you sign up, complete a reading or buy, a hashed version of your email is shared with Google for conversion matching. When you sign up or check out, that click reference and the campaign name are also saved with your account, so that if you later buy from another browser or device our server can tell Google Ads which ad the purchase came from — the click reference, the amount and, with ad measurement on, your hashed email; never your birth details or name. Switching ad measurement off deletes the stored click reference from this browser and stops it being sent. Personalized advertising is never switched on for you by region; it is a separate choice. Elsewhere, or if the country lookup fails, our Google measurement starts only after you accept it. Hashing does not make email anonymous: Google may match it to a Google account. Your birth details, name and reading contents are never sent to these measurement services. Email is never an ordinary Analytics parameter. Purchase measurement uses the confirmed payment amount and currency. Use Privacy choices in the footer to allow measurement, select Essential only to stop optional measurement, or open More choices to decide separately about analytics, ad measurement and personalized ads. The quick Allow measurement choice does not enable personalized ads. Your saved choice takes priority over your estimated country, and we never record the regional default as if it were your choice. Essential sign-in, payment and reading features work regardless. We store your explicit preference in this browser, along with a marker per completed reading or purchase so it is not counted twice. Operational reading and payment records remain available to provide the service, independently of Google.

While you're working, your birth details stay in your browser tab (session storage) — closing the tab clears them. When you ask for your sign-in link, the birth details you typed are saved to the new account straight away, so the link opens your reading on whichever device or browser you tap it from; a copy also waits in your browser (not just the tab) and is cleared the moment the link is used, when you sign out, or after a day unclaimed. When you're signed in, your readings — birth details included — are saved to your account so you can come back to them. Accounts are stored with Google Cloud in Singapore, and other users cannot read your account. Your signed-in browser receives the information needed to show your reading.

Signing in works by email — a link, or a six-digit code in the same email that works once for ten minutes (we keep only a scrambled copy of it) — or, where offered, with your Google account, in which case Google tells us your email address and that it is verified, and nothing else. There is no password to create or for anyone to steal. A session cookie keeps you signed in; it exists for that purpose alone.

Checkout stores the reading you are purchasing and your email with our service. Stripe receives your email and payment details; we do not send Stripe your birth details and we do not store card numbers. An essential purchase cookie lets this browser open the new report for up to fourteen days. It does not unlock another account’s past readings.

After you verify your email by a sign-in link, your purchase can be linked to your account. Deleting that account removes its purchase drafts and saved birth details from our service. For an unfinished or unclaimed checkout, contact hello@daikichi.app to request deletion. Payment records held by Stripe follow its retention requirements.

Sign-in links and codes and purchase receipts, and nothing else unless you opt in. Every account is confirmed through its inbox before a reading is shown — the free reading waits behind the sign-in link, so an address that isn't yours never gets one. If you turn on the daily almanac note, we send that; turn it off and we stop. We don't send marketing or sell your address. If you accept advertising measurement, the hashed-email sharing described above also applies.

The calculations — chart, directions, dates — run entirely in our own engine. The following can involve an outside service, all in service of your reading: the prose of a consult answer may be drafted by an AI writing service, which receives your computed findings and question. We also use AI to host the optional interview and write the personal parts of your report from your answers. We do not add your account email or name to these prompts; avoid including identifying details in free text. Practical context (weather on candidate dates) is fetched from a public weather service using the event location's coordinates. If either service is unreachable, your reading still works — the writing falls back to our own templates.

Everything we hold about you is on your account page: your saved readings, the birth details inside them, and your email. If you would rather have it sent to you, or something in it is wrong and you cannot change it yourself, write to hello@daikichi.app from the address on your account and we will send or correct it as soon as possible, within the applicable response period.

Your account page has a delete-everything control. It removes your account, your saved readings, your birth details and your interview answers — no email to write, no request queue, no retention period. It works today and it will keep working.

One thing outlives it: the record of what our AI writing service cost us to answer your questions, kept for accounting. It holds an internal account number and word counts — never your birth details, your questions or your email — and once your account is gone, that number no longer points at anyone.

Birthplace lookup uses the GeoNames gazetteer (CC BY 4.0) — a bundled table, so your birthplace is never sent to a third party to be geocoded. Country lookup uses DB-IP Country Lite (CC BY 4.0), refreshed monthly, with attribution in our footer.
