Privacy
Your birth data, handled gently
Your birth date, time and place together are personal data. We collect the minimum, keep it briefly, and let you delete it in one tap.
No accounts
There are no sign-ups or logins. Each chart is saved under a random, unguessable link (a 12-character id), so only people you share that link with can see it.
What we store, and where
| Data | Where | How long |
|---|---|---|
| Birth date, time, place and the computed chart | Our database | 90 days, renewed each time the chart is opened |
| Your AI reading | Our database | Same as its chart |
| Name (optional) | Only in the chart record, to personalize the reading | Same as its chart |
| Chat history | Your browser only (localStorage) | Until you delete the chart or clear site data |
A chart that isn't opened for 90 days expires automatically and is permanently removed along with its reading.
Deleting your chart
Use Delete this chart in the chart's menu. It immediately removes the chart and its reading from our database and clears the chat saved in your browser. The share link stops working for everyone. This can't be undone.
The AI reading and chat
To write your reading and answer your questions, we send your computed chart (and, if you gave one, your name) plus your chat messages to an AI model provider through Vercel AI Gateway. Every request asks the gateway for Zero Data Retention and no prompt training, so it only goes to providers that have agreed not to store prompts or train on them. We never use your birth details as a tracking identifier.
Analytics and logs
- We use Vercel Web Analytics, which is cookieless, to count visits and pages viewed. Birth data is never sent to analytics.
- Our logs never record your birth details; they're redacted from error reports.
- We don't use advertising trackers or sell data.
- To prevent abuse, we apply rate limits keyed to your IP address, and a daily chat limit keyed to the chart's random id. These counters contain no birth details and expire within a day.
Questions
Artastro is for entertainment and self-reflection. If you have a question about your data or want help removing a chart you no longer have the link to, contact the site operator.
