The short version: we compute what twelve traditions say about the sky. We don't tell you what will happen, and we're careful about the word "verified".
Only that a reading can be reproduced exactly from your sealed record and published ephemeris data. It is a statement about arithmetic, never about the future.
Nothing in ArcSeal is a forecast of events, and nothing is guaranteed to happen. Readings are interpretive: they report what each tradition has historically said about a sky like today's.
Readings are not medical, psychological, legal, or financial advice, and shouldn't stand in for a doctor, therapist, lawyer, or advisor. Don't make a consequential decision because a reading suggested it.
Where the twelve conflict, we print the conflict rather than averaging it away. Disagreement is information, not a fault.
Synastry requires the other person's consent to their own record. Never use a reading to make a decision about somebody's employment, housing, credit, care, or safety.
If you're in crisis, contact local emergency services or a crisis line. An astrology app is not a place to look for help with that.
