Your child's chart stays with you
Little Destiny Blueprint is built local-first on purpose: the most private place for a child's birth data is your own device. This page says exactly what is stored, where, and why — in plain language.
Charts are computed in your browser
When you chart a child, the Four Pillars calculation runs entirely on your device. You can use the full blueprint, roadmap and family chemistry without creating an account — in that mode, no birth data is sent to us at all. Charts are saved in your browser's local storage so they're there when you return.
Parent charts never sync
Birth details you add for parents (Family Chemistry) are stored only on your device. They are not uploaded with cloud sync. If you request an AI Deep Reading of a pairing, the chart pillars are sent once to generate that reading, and only the finished written reading is saved to your account — never the parent's birth data.
Accounts are optional and passwordless
Signing in ("Save & sync") uses a one-time magic link to your email — there is no password to create or leak. Sync exists so your children's charts and milestone check-offs follow you between devices. You can keep using everything without an account.
What we store when you sync
With an account: your email address, your children's birth details as you entered them, milestone progress, and any AI readings or reports generated for you. Data is stored with our database provider (Supabase) with row-level security — your rows are readable by your account only.
AI readings
The Parenting Report and Deep Readings are written by an AI model. To generate one, the chart context (pillars, ages, first names as you entered them) is sent to the model via our server. Readings are cached to your account so repeat visits don't re-send anything. Generation is capped and never happens without you pressing the button.
No ads, no trackers, no data sales
We run no advertising, no third-party analytics trackers, and we do not sell or share personal data. The only third parties involved are our hosting (Netlify), database (Supabase), email delivery, and the AI provider used to write readings you request.
Deleting your data
Deleting a child in the app removes them from your device — and from your account too if you're signed in. Clearing your browser storage removes everything local. To remove your account entirely, contact us via knowyourprofile.com.
