Privacy and data use
Last updated 30 August 2026. Biderra is currently a free public procurement discovery service. This notice explains device storage, infrastructure records and the advertising controls that will apply when monetisation is activated.
Who operates Biderra
Biderra is an independent digital publishing and procurement discovery project operated from Türkiye. Privacy requests and questions can be submitted through the contact page.
Contact-form data
When you use the contact form, Biderra stores your name, email address, selected topic, message and submission time so the request can be reviewed and answered. Do not include confidential procurement files or passwords. Contact records are retained only as long as reasonably needed for the request, security and record keeping.
Data stored on your device
Your language preference and saved searches are stored in your browser using local storage. They are not currently attached to an account or sent as email or SMS alerts. Clearing site data removes them.
Infrastructure data
The service runs on Cloudflare infrastructure. Standard technical records such as IP address, request time, browser information and security events may be processed to deliver and protect the site under Cloudflare’s applicable policies.
Advertising and analytics
Biderra is connected to Google AdSense for site review and future advertising. Google and its advertising partners may process device information, cookies, approximate location and interaction data to deliver, measure and protect advertising. Personalised advertising will use a certified consent-management interface in applicable regions.
Your advertising choices
Where consent is required, visitors will be able to accept, reject or manage available advertising purposes and later reopen those choices. Advertising will not change the official procurement data or the calculation of Biderra market statistics.
Future alerts
Email and SMS alerts are planned as an optional later service. Contact details, consent and unsubscribe controls will be introduced only when that feature is released.
