Selfra

Principles

How Selfra works as a company.

We wrote these down so we can be held to them. By customers, by investors, by anyone we hire, by ourselves on the days the choices are hard.

  1. 01

    Your data is yours. We are stewards, not owners.

    We hold the ledger of your body in trust. You can take it back, in full, in a portable format, on any day, for any reason.

  2. 02

    We will never sell information about your body.

    Not to insurers, not to employers, not to advertisers, not to data brokers. There is no version of Selfra in which this changes.

  3. 03

    We will tell you what we see, even when it is uncomfortable.

    If your iron is trending toward a deficiency, we will say so. The point of an instrument is to read what it reads. Comfort is not its job.

  4. 04

    We will not optimize you for engagement. We will optimize you for years.

    There are no streaks, no notifications designed to pull you back, no dark patterns. The product is judged by your healthspan, not your session count.

  5. 05

    We will say no to features that improve metrics and harm health.

    Some things would lift retention and shorten lives. We do not ship those. Internally, we keep a list of the ideas we declined and why.

  6. 06

    We will be wrong sometimes. We will tell you when, and we will fix it.

    Vision systems make mistakes. Models drift. We will publish the errors we find, the corrections we make, and the limits of what we know.
