TintSlate

Keep client formulas, exact bowl weights, service results, photos, auditable corrections, PDF exports, and verified backups private on your device.

TintSlate is a private, offline client, hair-color formula, and service ledger for professional colorists. Record the facts behind each service without an account, subscription, advertising, analytics, AI, or cloud dependency.

• Keep client identity, code, tags, notes, archive status, and a complete service timeline • Record one or more formula bowls with brand, series, shade, role, exact grams, duration, result, and notes • Scale a saved formula to a target weight while preserving component proportions • Attach selected result photos that are re-encoded locally with location metadata removed • Preserve original service snapshots while corrections, photo removals, voids, and restores append an audit trail • Search clients and export a readable client PDF • Create checksum-verified backups, preview them, then merge or replace local data safely

TintSlate records user-entered facts. It does not generate formulas or provide medical, chemical, safety, or professional advice. Always follow manufacturer instructions, professional judgment, safety testing, and applicable guidance.
