Accessibility​

We have many accessibility elements implemented by the Flutter development framework that we use, especially for screen readers. Namely that as standard the phone's accessibility settings are taken into account:

  • TalkBack (Android) and VoiceOver (IOS)
  • BrailleBack on Android
  • Dynamic font size
  • Contrast management
  • "Invert colors" mode, Light and Dark built-in themes
  • Addition of custom themes
  • Focus support for navigation
  • Accessible gesture management

The wallet supports screen readers, keyboard navigation, high contrasts and text adaptation.

GDPR​

We are committed to ensuring your data protection rights are upheld in accordance with the General Data Protection Regulation (GDPR). We protect the important rights under the GDPR, and we assist users to exercising them:

  • The Right to Access, Update, or Delete: Users can access, update, or request the deletion of their Personal Data directly within their account settings on our platform. If they need assistance with these actions, they can access the support by email and through the app itself.
  • The Right of Rectification: If they believe their Personal Data is inaccurate or incomplete, they have the right to request corrections.
  • The Right to Object: They can object to the processing of their Personal Data.
  • The Right of Restriction: Request the restriction of the processing of their Personal Data when necessary.
  • The Right to Data Portability: Obtain a copy of your Personal Data in a structured, machine-readable format.
  • The Right to Withdraw Consent: If we rely on their consent to process their Personal Data, they have the right to withdraw it at any time.

In order to allow users to assert their rights, we have set up numerous means of communication between the user and the wallet provider. These technical means are also respectful of their privacy and for this reason are supported in the wallet itself by decentralized tools, in particular by a chat built on https://matrix.org/ and an integrated email. The privacy policy is available in the wallet itself and on our website at https://talao.io/privacy/ .
