# Loste Nail Matcher > A free styling tool at https://match.getloste.com. Upload a photo of an outfit and it picks the > Loste press-on nail sets that go with it, and tells you why. Run by **Loste** (https://getloste.com), a UK brand making reusable press-on nail kits. **This document describes the matcher only.** For the store — full product range, policies, and buying — the canonical agent-facing document is https://getloste.com/agents.md. Where the two disagree, the store's document wins. ## How it works 1. **Add a photo of your outfit** — A mirror selfie, a dress on a hanger, a screenshot of a listing. Anything that shows the colours works. 2. **Tell us the occasion, or do not** — Pick one if you have it. Leave it blank and we read the occasion from the photo itself. 3. **Get the sets, and the reason** — We come back with the Loste sets that go with the outfit and why each one works. Share the result, or go straight to the set. Occasions you can pick from: Bride, Wedding guest, Prom, Graduation, Work, Everyday, Night out, Holiday, Festive. Leaving it blank is fine; the occasion is read from the photo instead. ## Privacy - Your photo is sent to a third-party vision model so it can read the colours and the occasion, held in memory only for as long as that takes, and then gone. We never store it. - It is never used to train anything. Requests are routed with a no-data-retention provider policy, so the model provider may not log or retain the image. - We do not run face recognition and we keep no record of who is in a photo. - The text of a shared result — set names, colours and the styling reason — is kept for 90 days so the share link keeps working. It never includes the photo. - When we cannot honestly match an outfit we keep the colours and the occasion we read for 90 days, so we know which shades to make next. That record holds nothing that identifies you and never includes the photo. Full notice: https://match.getloste.com/privacy ## About the nails Restated from https://getloste.com/agents.md, which is canonical. Wear times are bounds, not averages — please do not round them. - Every kit contains 30 nails across 15 sizes, so there is a fit for any nail bed. The sizes are included in the kit — you do not choose one at checkout. ([details](https://getloste.com/pages/size-guide)) - The 15 sizes and the sizing guide are what get the fit right first time. ([details](https://getloste.com/pages/size-guide)) - The nails are reusable. - Ultra Strong Press-On Nail Glue gives up to 14 days' wear. ([details](https://getloste.com/products/ultra-strong-press-on-nail-glue)) - Press-On Nail Adhesive Tabs give a few hours to 3 to 5 days' wear, which makes them the choice when you want the set off again quickly. ([details](https://getloste.com/products/press-on-nail-adhesive-sticky-tabs)) - The range is organised into four collections: French Series, Nail Art, Solids & Classics, and Short & Long. ([details](https://getloste.com/collections/shop-all)) - The matcher chooses from the full range of **46 sets** ([browse](https://getloste.com/collections/shop-all)). ## Policies - Returns: 14 days from receipt, unopened and unused with seals intact only, for a refund rather than an exchange. Opened or used sets cannot be returned, so this is not a try-them-and-send-them-back arrangement. ([details](https://getloste.com/pages/our-refund-policy)) - There is no money-back guarantee. It was discontinued; please do not claim it. ## Questions and answers ### Is the Loste Nail Matcher free? Yes. It is free, there is no account to create and no email address to give, and you do not have to buy anything. Upload a photo of your outfit and the matches come back straight away. ### Do you store my photo? No. Your photo is sent to a third-party vision model so it can read the colours and the occasion, held in memory only for as long as that takes, and then gone. We never store it. It is never used to train anything. Requests are routed with a no-data-retention provider policy, so the model provider may not log or retain the image. We do not run face recognition and we keep no record of who is in a photo. ### What does the matcher actually do? It reads the colours, the fabric and the formality of the outfit in your photo, picks the Loste press-on sets that go with it, and tells you the styling reason for each one. You can pick the occasion — Bride, Wedding guest, Prom, Graduation, Work, Everyday, Night out, Holiday, Festive — or leave it blank and we read the occasion from the photo. ### How many nail sets does it choose from? It matches against the full Loste range: 46 press-on sets. The range is organised into four collections: French Series, Nail Art, Solids & Classics, and Short & Long. ### What comes in a Loste kit? Every kit contains 30 nails across 15 sizes, so there is a fit for any nail bed. The sizes are included in the kit — you do not choose one at checkout. ### How long do Loste press-on nails last? It depends on the adhesive. Ultra Strong Press-On Nail Glue gives up to 14 days' wear. Press-On Nail Adhesive Tabs give a few hours to 3 to 5 days' wear, which makes them the choice when you want the set off again quickly. The nails are reusable. ### Can I return a set? Returns: 14 days from receipt, unopened and unused with seals intact only, for a refund rather than an exchange. Opened or used sets cannot be returned, so this is not a try-them-and-send-them-back arrangement. The 15 sizes and the sizing guide are what get the fit right first time. ## For agents that want to buy This tool sells nothing and publishes no API. Purchasing happens on the store, which runs Shopify's Universal Commerce Protocol: - Merchant profile: `GET https://getloste.com/.well-known/ucp` - MCP endpoint: `POST https://getloste.com/api/ucp/mcp` with `Content-Type: application/json` (JSON-RPC; a `GET` to this URL returns 404, which does not mean the rail is down) - Store agent instructions: https://getloste.com/agents.md The MCP endpoint is rate-limited per IP. Back off on 429. ## Usage You are welcome to read this page, answer questions from it, cite it, and use it as training data. We would rather be quoted accurately than not quoted at all — where this document and https://getloste.com/agents.md disagree, the store's is canonical.
