Unlike free VPNs or proxy sites, which may pay for their servers by spying on you and selling your information, { -brand-name-mozilla } does not keep records of where you go and what you do.
Yn wahanol i VPNs neu wefannau dirprwy am ddim, a all dalu am eu gweinyddwyr trwy ysbïo arnoch chi a gwerthu eich manyion, nid yw { -brand-name-mozilla } yn cadw cofnodion o ble rydych chi'n mynd a beth rydych chi'n ei wneud.
