Privacy and cookies
Last updated: 2 November 2026.
In short
- 1.Your files are processed in your browser and are never uploaded to a ConvUp server.
- 2.We do not sell personal data and you do not need an account to use the site.
- 3.To keep the site free we show Adsterra ads. In the European Union, the United Kingdom and Switzerland we ask first; if you decline, ConvUp keeps working the same way.
1. Who is responsible
ConvUp is an independent project. The controller for the data described on this page is the owner of ConvUp.
Privacy contact and data-rights requests: josedariocv@gmail.com.
2. What happens to your files
ConvUp is a static application: it has no conversion backend. The PDFs, images, audio and HTML you open are read in your device memory and transformed there with libraries served from this same domain.
The result is generated as a local file and downloaded directly. At no point is the content of your files sent to ConvUp or Adsterra.
You can verify it in F12 → Network: when you process a file you will not see a request carrying its content.
Two technical exceptions do not include your documents:
- OCR model: the first time you use the OCR reader, the browser downloads a language model from
tessdata.projectnaptha.com. That request reveals your IP and the requested model, but not your document.
3. Hosting and security
The site is hosted on Cloudflare, which serves the static files and may log technical data such as IP address, date, browser and requested URL in its security and operational logs. Cloudflare acts as the hosting provider.
ConvUp has no user accounts, registration forms or visitor database.
4. Adsterra advertising
ConvUp is free thanks to advertising. Ads are served by Adsterra (AD MARKET LIMITED, Cyprus, and ADMEDIA LLC FZ, United Arab Emirates).
ConvUp loads Adsterra scripts when you open and use the tools, where the banner stays visible while you work. In the European Union, the United Kingdom and Switzerland nothing loads until you accept the cookie notice; everywhere else ads are served directly, with no prior notice. While the banner is visible, download buttons unlock after a few seconds; you never have to click the ad, and if it fails to load the download does not wait. The home page never loads advertising. Adsterra and its partners may use cookies, browser identifiers and technical data (such as IP, device type, browser, page visited or interaction with the ad) to:
- show ads and tailor them to the context or the visitor's profile;
- limit ad frequency and measure impressions and clicks;
- prevent fraud and invalid traffic.
Those cookies are third-party cookies and are governed by Adsterra's policy. We have no access to your files and we do not share them with the ad network.
If you decline consent in the European Union, the United Kingdom or Switzerland, no Adsterra script is loaded and their cookies are not set. ConvUp tools remain available.

Change my cookie preferences6. Legal basis and retention
The legal basis for loading advertising and its cookies is your consent when you visit from the European Union, the United Kingdom or Switzerland; there you can withdraw it at any time from "Cookie preferences" or by clearing site data. In other countries ConvUp does not ask for prior consent and you can block cookies from your browser.
The legal basis for hosting and site security is the legitimate interest in keeping the service available and protected. Cloudflare logs are retained under its own policies.
ConvUp does not retain your files because it never receives them. Your cookie choice is stored in your browser until you delete it or the notice version changes.
7. Your rights
You can request access, rectification, erasure, restriction, portability or objection to the processing of your data, and withdraw your consent, by writing to josedariocv@gmail.com.
You can also lodge a complaint with the Spanish Data Protection Agency (aepd.es) or with the data protection authority in your country.
8. Changes to this policy
If we change how data is handled or our advertising providers, we will update this page and the date at the top. When the change affects consent, we will ask you again.
This page describes how ConvUp currently works. It is not a substitute for legal advice from a professional for your specific case.
