Privacy in Halo

Your reasons
stay yours.

Halo should know as little as necessary to create the experience. For every personal feature, we ask: what leaves your device, and why?

01 / PRIVATE

Your inner life

Your journal, sobriety date and history, birth details, Your Days photos and goals stay on your iPhone. Halo’s servers never receive them.

02 / SHARED

Only what connection needs

Together, Circle and Discover are optional community features that require Sign in with Apple. Details are in the Halo app Privacy Policy.

03 / YOUR CHOICE

Yours to end

You can use Halo without an account. If you create one, you can delete it in the app at any time: You › your Halo account › Delete account.

On your iPhone

Your journal, your sobriety start date and history, your birthday and birth details, your Your Days photos and the goals you choose are stored only on your iPhone. Your daily guidance, including its astrology, is worked out on your iPhone from the current sky and those choices. It is symbolic, it never predicts your health or recovery, and it is not generated by AI.

Local does not mean immune to backups or loss. Like other app data, this information may be included in your iPhone or iCloud backups according to your Apple settings. Deleting the Halo app removes it from your iPhone, and Halo has no copy to restore on another device.

When data leaves

Halo’s servers receive information when you sign in with Apple and use the community, Together, Circle and Discover: your account, the identity you choose, what you share (including a Discover voice introduction, if you record and share one) and safety records such as reports and blocks. What Halo stores, why, and for how long is set out in the Halo app Privacy Policy. Calling a crisis line or opening a link from the app takes you straight to that service.

The website is separate. A waitlist email or phone number is kept in Halo’s private storage on Vercel. A phone number is accepted only with your consent to texts about Halo opening; Halo doesn’t send texts yet, and you can reply STOP or ask us to delete your number; earlier sign-ups may also remain in Halo’s Mailchimp account. Reservation flows, when enabled, use Halo’s database and Stripe; reservation data details describe those fields and event identifiers. Hosting providers also receive ordinary connection information such as IP address.

Together, Circle and Discover

For the Halo iPhone app, including Together, Circle and Discover, the Halo app Privacy Policy is the full policy.

Shared world, different private reasons. Other members never see your journal, sobriety date, birth details or Your Days photos. They see only what you choose to share, under the identity you choose. Halo doesn’t send your milestones or day count to the community, except a Circle level you choose to show beside your name.

ONE WORLD

A design principle: shared world, different private reasons.

Photos

Your Days photos stay on your iPhone. Halo shows you the photos you took on a day so you can choose one, and nothing leaves your iPhone.

A photo you share to a Circle is different. Before you share it, your iPhone checks it for faces and doesn’t share it if it finds one; the check can miss faces. Before it is stored, Halo re-encodes it, removes its metadata, including location, and resizes it. It is kept in private storage that only that Circle’s admitted members and Halo’s moderators can see. When you save a milestone card, Halo adds only that image to your Photos.

No AI

Halo’s daily guidance is worked out on your iPhone from the current sky and the goals you choose. It is not generated by AI, and Halo does not send your journal or anything you write to an AI service.

Analytics and alerts

The iPhone app has no advertising, no tracking and no third-party analytics SDK. Apple diagnostics can depend on your device settings. Optional milestone reminders are local notifications with generic text, scheduled on your iPhone; notification previews can still appear on a lock screen. When website reservations are enabled, allowlisted funnel events can record random visitor/attempt identifiers and may be linked to a reservation. They do not need recovery content.

Questions

No end-to-end encryption, anonymity or complete deletion guarantee is claimed here. The Halo app Privacy Policy and the reservation notice set out exactly what is kept.
