Is Apple Health data private in Til100?

The current release targets iPhone and Apple Health. This page explains what Til100 reads, why it is needed, and how to disconnect, export, or delete it; Android and Health Connect remain planned.

This website never asks for health data.

The Til100 site presents the product and nothing else. It asks no health question, runs no model, shows no personal result, has no account, and holds no session. There is nothing here for it to leak.

Policy identity

Who is responsible for Til100.

Til100 is the health-management product of 至百. The service is operated under the Til100 and 至百 product identity. This policy was updated on 13 August 2026 and applies to the Til100 website and native app.

Processing location

Storage is in Singapore; consented AI processing is in mainland China.

The iOS app stores account and health data in one reviewed Supabase environment hosted in Singapore. With a just-in-time disclosure and your consent, report OCR, uncertain-row review, Tilo answers, and meal-photo analysis use Alibaba Cloud Model Studio in mainland China (Beijing). The public website does not collect health data.

In the app

Til100 only collects health data you choose to share.

What you tell the app

A small baseline: age, the population table to use, region, your goal, and whether you want to see lifespan numbers at all. Sensitive questions can be skipped, and skipping lowers confidence rather than counting against you.

What your phone already records

For the current iPhone build, only the Apple Health categories you grant, one at a time. Health Connect is planned for a future Android release, after its own evidence and privacy review.

What you correct

Manual entries and corrections you make. Your correction wins over derived data.

Deliberately not collected

What Til100 does not collect.

Detailed family medical history, relatives' ages, or causes of death.
Your mailbox. Til100 does not request full-mailbox access.
Calendar titles, bodies, attendees, locations, or notes.
Anything from this website. No questionnaire, no account, no health data.

How your data is used

Til100 does not sell your health data.

Your health data is used to provide the Til100 features you choose. It is not sold or sent to advertising platforms. For transparency, Til100 stores app data in its reviewed Singapore Supabase environment. The consented AI features described below use the disclosed Alibaba Cloud Model Studio processor in mainland China.

What analytics sees

Analytics does not receive your health values.

General analytics receives allowlisted interaction events only — never health values, lifespan estimates, Bonus Balance amounts, condition names, laboratory results, or free text. Analytics identifiers are pseudonymous, not anonymous, and we say so.

Permissions

Choose each data source—and disconnect it at any time.

Health access is requested per category, after a screen explaining what each one is for. Declining leaves a working app with a manual path. Revoking later is done in your phone's own settings, and Til100 stops reading immediately.

Leaving

Export or delete everything without contacting support.

Both are reachable from You, without contacting support. Deletion propagates to derived aggregates and model records, not just to your login.

AI sees only the data needed to explain a result.

Before each materially different AI feature first sends data, Til100 explains what is sent, why, and where. Tilo receives minimum structured facts—not raw HealthKit samples, report files, or meal photos. Full reports go only to the dedicated OCR path, and uncertain-row review is separately optional. Alibaba Cloud Model Studio in mainland China (Beijing) is the current AI processor. These transfers are not used for advertising or provider model training. Declining leaves the relevant manual or deterministic product path available.

Review every permission and data source in the app.

Consent versions, connected sources, correction history, export, and deletion all live in You.
