Where a listing photo is processed, and where it goesA dashed panel labelled In your browser holds three stations in a row: orient from EXIF, downscale to 1600 pixels, and re-encode. A photo tile with a GPS tag attached travels through them; at the third station the GPS tag is struck through and faded. Below the panel, a thin two-way arrow reaches a box for the caio.ltd server, which carries no photo bytes, while a separate arrow carries the photo itself to a box for object storage.In your browser1 · Orientfrom EXIF2 · Downscaleto 1600 px3 · Re-encodeEXIF + GPS goneGPSa signaturethe photocaio.ltd serverno photo bytesObject storagethe photo lands hereThe photo never passes through our server.
The location data never leaves your device. Your browser turns the photo the right way up, shrinks it to 1600 px and re-encodes it from raw pixels — which destroys every EXIF, XMP and IPTC block, GPS coordinates included — before a single byte is sent. Our server only issues a signature and then checks what was stored; the photo itself goes straight to object storage.
The thirty-day life of a listingA bar runs from the day a listing goes live to day 30, filling as time passes. A listing card travels along it. At day 27 an envelope marks the reminder email. At day 30 the card drops below the bar and is marked expired. A long arrow returns from there to the start, labelled Renew, and a short branch off the middle of the bar is labelled Mark sold.email at day 27goes liveMark soldout of the feedday 30 · expiredRenew · another 30 days
A listing runs for 30 days, then quietly leaves the feed. We email you three days before it goes. Renewing puts a fresh 30 days on the clock; marking it sold takes it out at once. Nothing is deleted — an expired listing is one click away from being live again.

Confirm the deal

When both parties confirm, phone numbers are revealed simultaneously — keeping everyone safe until trust is established.

The mutual-consent gate on phone numbersA buyer card and a seller card face each other, each holding its own phone number and each with an empty slot for the other side. Two lanes run between them, one in each direction, and a barrier in its housing blocks both. Two switches beneath it, one marked Buyer and one marked Seller, are wired together into that barrier. With one switch on the barrier still holds and a number pushing against it is turned back. With both on the barrier lifts out of the housing and the two numbers travel, one down each lane, at the same moment.BuyerSellergateBuyer phoneSeller phoneBuyerSellerOne confirmation opens nothing.
Neither number moves until both sides have confirmed. You have to message the other person first — a deal cannot be opened with a stranger. Then each side confirms separately. One confirmation releases nothing; the second releases both numbers at the same moment. Either side can withdraw, and both numbers go straight back behind the barrier.

More on the mechanism, including what happens to a photo’s location data: selling without giving out your phone number.

Buying a second promotion week extends the windowTwo bars share one day axis running from day 0 to day 14, with a marker at day 4 where a second week is bought. The upper bar shows what a reset would do: the new week starts at day 4 and ends at day 11, discarding three days that were already paid for. The lower bar shows what caio.ltd does: the new week starts at day 7, where the first ends, and runs to day 14.If it reset — 11 days3 days lostcaio.ltd — 14 daysstarts where the first endsyou buy a 2nd weekday 0day 7day 14Featured ₹290/week · Keyword boost ₹150/week
A second week extends the window; it does not reset it. Buy another week on day 4 and the new one starts where the current one ends — so the promotion runs to day 14, not day 11. The days you have already paid for are never thrown away. The same applies to a keyword boost.
