The tradition
Palmistry
There is no ephemeris here and nothing to check against an almanac. What honesty is available is procedural — so EnteAstro asks rather than asserts, and refuses whole categories of claim outright.
It asks; it does not assert
EnteAstro's guided reading is a structured questionnaire. You look at your own hand and answer eight questions, and it interprets what you reported. Nothing is claimed to have been detected, because nothing was.
Every answer carries its own confidence, sitting beside it rather than buried at the end. “I can't make it out” is offered as plainly as any other answer, and a feature you could not see produces no interpretation at all — a reading with a gap in it is more use than one with a guess in it.
What it will not say
No medical reading. No lifespan. No fertility. No criminality. No mental-health inference. These readings exist in the popular literature and they are not in this product, in any framing.
In particular: the length of the Life Line does not indicate how long anybody will live. It is the single most widely repeated claim in popular palmistry and EnteAstro refuses it explicitly, in the reference data itself, with a test that fails the build if a future edit drops the refusal. The line's arc is read, for vitality and appetite — never its length.
Photographs
A palm photograph is biometric, and EnteAstro treats it that way. Detecting palm lines from a phone photo well enough to be worth anything is a real computer-vision problem, and shipping a detector that guesses would be exactly the dishonesty this product exists to avoid. Guided mode is what ships today; the database and the privacy model for photo-assisted readings are built, and the detection is not.
When it does ship, the design is already fixed: features detected with a confidence, shown to you for confirmation before a word is interpreted, and an offer to keep the reading and discard the image. No staff role can read a palm photograph or a palm reading — the database has no policy that would allow it.
