# Know What's Still Under Warranty

> Scan the receipt or warranty card — on-device OCR pre-fills the store and purchase date — pick the coverage length, and the tracker computes the expiry and files it under Active, Expiring soon, or Expired. One tap exports an expiry to your calendar as an .ics event, so Google or Apple Calendar does the reminding; no account and no notifications permission needed. The whole list exports to CSV or a ZIP backup with the receipt photos.

## How it works

1. **Add the purchase** — Scan the receipt or warranty card — store and purchase date fill themselves — or type the purchase in manually.
2. **Set the coverage** — Pick the warranty length (one tap for the common 1/2/3/5-year terms). The expiry date is computed with proper month math.
3. **Get reminded by your own calendar** — Add the expiry to your calendar with one tap, or export every expiry as one .ics file. Your calendar app handles the reminders.

## FAQ

### How do the reminders work without an account?

Through your own calendar. Each expiry exports as a standard .ics event that Google Calendar, Apple Calendar, and Outlook all import — they remind you, this tool never needs to.

### What does the scanner read off the receipt?

The store name and purchase date, which pre-fill the form. You add the product name and coverage length. Every field stays editable, and the receipt photo is kept with the item.

### Where does the warranty list live?

In your browser's local database on this device. Use the ZIP backup — it includes the receipt photos — to keep a copy you control or to move the list to another device.

### Does month math handle the annoying cases?

Yes — a one-month warranty bought January 31 expires the last day of February, not March 3. Month-end purchases clamp the way the manufacturer's terms actually read.

## Tips

- **Scan the receipt, not the box** — The receipt carries the two facts that matter — purchase date and store. OCR pre-fills both; you just name the product.
- **One .ics for everything** — Export all expiries as a single calendar file once a season — every warranty lands in your calendar with its serial in the event notes.
- **Extended warranty? Add months** — Credit-card or store extensions just change the coverage length — set custom months and the expiry recomputes.

## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while Know What's Still Under Warranty runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
