Shelf-Life & Expiry Tracker

More than most shops track: sealants and adhesives (hard cure-by dates), elastomers — o-rings and hoses age from CURE date, not install date (the quarter-based cure code on the package is the clock), chemicals and paints, fire-extinguisher and first-aid contents, ELT batteries. Installing expired-shelf-life material creates a parts-documentation defect on an otherwise good repair. A 60-day amber board makes the quarterly shelf purge a ten-minute job.

The formality is thirty seconds per event; the informal alternative is priced in core charges lost, warranties unfiled, stockouts mid-inspection and audit findings. Small operations arguably need the discipline MORE — there's no purchasing department catching these by process, so the structure has to live in the tool. One recovered core charge typically pays for years of the habit.

By design: operational records are sensitive, and the simplest privacy guarantee is never transmitting them. Local-only storage means zero servers, zero breach surface and zero subscription. If you work from several devices, keep one as the master record and move snapshots with the CSV export.

Always — the CSV export is a complete, lossless dump of your parts record, generated locally in one click. Import it into commercial software, archive it with your files, or post-process it in a spreadsheet. No lock-in is deliberate: data you can't take with you isn't really yours.
