Why advertising?

• It is clear that advertising, to a greater or lesser extent, is annoying. Then, why appears on this site? The answer is simple: it is its main source of funding.
  
  
• For those entities that offer free services to the customer, advertising becomes their main source of funding.
  
  
• The user must not do anything special with the advertisement appearing in Calc-útiles, as with any other commercial at television or at the press. If the content of the ad is relevant to the user, you can click the link to access the advertiser's website and learn. If the ad is not relevant to the user, You can safely ignore it anymore.
  
  
• The economic benefit generated by advertising posters is very low, even zero in sites with few visitors. As a general rule it can be considered that the benefit is a small commission on sales generated entering through the links of the advertiser's website.
  
  
• In order to access Calc-útiles services without advertisings, we have developed access through subscription, with which you can access all utilities with additional features compared to free service (access without advertising, corporate logo, early availability...) For more information, you can check the page Subscriptions.
