KeyLevel 88 Regulation Map
KeyLevel 88 Regulation Map Terms of Use
Terms for using KeyLevel 88 Regulation Map as a technician-entered factual regulation worksheet.
Effective: September 21, 2026
Purpose and limits
The app records values, units, provenance, verification state, and factual deltas supplied by a technician. It does not automatically measure, diagnose, tune, certify, judge regulation quality, or assert a factory tolerance.
Technician authority
Reference values, targets, and professional decisions remain the technician’s responsibility. UNKNOWN, UNVERIFIED, and INCOMPLETE states are preserved rather than inferred.
Plans and purchases
The free experience includes one complete 88-key regulation job and ownership-safe export, backup, restore, recovery, and deletion. Pro Monthly, Pro Yearly, and Pro Lifetime unlock the same multi-piano, repeated-visit, longitudinal comparison, baseline, and multi-job capabilities. Apple handles billing, renewal, cancellation, refunds, and taxes.
Your data
Previously created records remain readable and exportable if a subscription expires. You remain responsible for the measurements and records you enter, verify, export, import, or share.
