No accounts, no tracking cookies

There are no accounts, no email sign-up, no analytics services, no tracking cookies and no third-party fonts. Every file on these pages comes from barterbazarr.com, except the one labelled banner ad from adengine.us described under Advertising (its tag also counts one page view per page, as a daily total). The Swap Sheet and Trade Tab pages load nothing from other sites.

The Trade Scale and Swap Sheet

What you weigh on the scale or put on a Swap Sheet is not saved in any database. The details travel in the page's address (link). Like any website, the web server's access log records the addresses of pages requested, with the requesting internet address, for a limited time, for security and fault-finding.

Trade Tabs

A Trade Tab stores what you type into it: the names you give, the tab name, an optional hourly rate and each entry (date, who gave, what, value, hours). It is opened by a random private link; we store only a one-way fingerprint (SHA-256 hash) of that link, so we cannot recover a lost link. A tab's private link is part of the page address, so it also appears in that access log for a limited time, like every other page address; the log is used only for security and fault-finding, never to look up tabs. Anyone who has the link can see and change the tab. Tabs not opened for 400 days are deleted, with their entries, and you can delete a tab yourself at any time; nightly database backups that contain it are kept for 14 days, and backups taken when the site is updated are kept longer, until they are replaced or removed.

Cookies and limits

Pages with a form set one security cookie (a CSRF token) so that forms cannot be submitted from other sites. To stop abuse, the number of new tabs and changes is counted per internet address per hour and per day; the address is stored only as a salted hash and the counts are deleted within three days.

Advertising

The home page, the guide, pricing and the Trade Scale’s worked example show one banner ad from AdEngine (adengine.us), the small ad network run by WeldonPC, the company behind this site. For now the ads are for WeldonPC’s own services; no trader, exchange or marketplace pays for them. A scale showing your own swap, the Swap Sheet, Trade Tabs and their statements, this page and the terms never show an ad, and the ad is left out when a page is printed. (Added 17 October 2026.)

To show an ad, your browser loads a script from adengine.us, asks it for one banner, loads the banner image, and reports once that the page was viewed and once that the banner was shown. Like any website, adengine.us receives your internet (IP) address and your browser type with those requests. The requests name this site; they never carry the address of the page you are on, so what you weigh never reaches it.

• No cookies, no profile. AdEngine sets no cookies, gives you no ID and does not track you from site to site.
• How your IP address is used. adengine.us looks up the approximate city for your IP address in a location database kept on its own server (nothing is sent to anyone else), so that ads meant for one area are shown only there. It also uses the address to count each ad view or click only once and to leave out robots and WeldonPC’s own office traffic. The address is not stored with the counts; the temporary entries made from it expire within six hours and are cleared from the server within two days.
• What is kept. Daily totals only: page views for this site, and views and clicks for each ad. The adengine.us web server also keeps a standard access log (IP address, time, address requested, referring site, browser) for security; it is deleted on a rolling schedule.
• Clicking an ad passes through adengine.us, which counts the click, and then opens the advertiser’s site, which has its own privacy policy.
• Nothing about you is sold or shared.

Payments

Payments are not switched on (preview). When they are, they will be handled by PayPal; Swapwright will not see or store card details.
