cerebral · privacy policy
your field is yours.
always.
Cerebral was built on a single principle:
your birth moment, your journal, and your field
are private by design — not by policy.
EFFECTIVE JUNE 2026 · KENSHOTEK LLC
THE PRINCIPLE
Everything computed on your device. Nothing transmitted to KenshoTek. Your field never leaves your phone — and when you share it, it goes straight to the other person, never through us.
WHAT WE COLLECT
Nothing
KenshoTek collects no personal data, usage analytics, crash reports, or identifiers. No SDKs, no beacons, no tracking pixels, no server-side logging. There are no servers — so there is no “us” to send anything to.
No account required
Cerebral works the instant you open it. No login, no email, no sign-in. Your identity is never transmitted to us or anyone.
No ads, no monetization of you
Cerebral is free and contains no advertising, no in-app purchases, and no data sales. Your data is not the product.
WHAT STAYS ON YOUR DEVICE
Your birth moment
The date, time, and place you enter to compute your cognitive field are stored only on your device, in the app’s private storage. Never uploaded.
Your journal & readings
Every reflection and reading is saved locally to your device. No entry is stored on any server.
The sky itself
Planetary positions are computed on-device from first principles (VSOP87 / Meeus). No network lookups, no ephemeris downloads — the math runs on your phone.
WHEN YOU LINK TWO FIELDS
Device-to-device, always
Cerebral lets you bring another person’s field into the room — by AirDrop, or by linking two phones directly over Bluetooth / Wi-Fi (and, on supported devices, Ultra Wideband for proximity). In every case the exchange is peer-to-peer. The portrait goes straight to the other phone.
Never through a server
Nothing in a field link passes through KenshoTek or any third party. There is no relay, no cloud, no copy kept anywhere. Walk apart and the link is gone.
THIRD-PARTY SERVICES
None
Cerebral uses no third-party services, AI APIs, ad networks, analytics, or data brokers. It is fully self-contained. Distributed via the Apple App Store — Apple’s standard policies apply to the download itself.
CHILDREN
Rated 4+, collects nothing
Cerebral is rated 4+ and collects no data from anyone, including children.
YOUR CONTROL
You hold all of it
Because your data lives only on your device, it is entirely yours. Delete the app and everything is gone — there is no copy anywhere else, and no account to delete.
Changes to this policy
If this policy ever changes, the updated version is posted here with a new effective date. The principle will not change: on-device, no collection.
