Entendemos que tu privacidad es muy importante, y estamos de acuerdo; es un valor fundamental en Thunderbird y Mozilla. Tu dirección forma parte de nuestra Información de Procesamiento de Pagos, Contacto y Donación, que detallamos en nuestra Política de Privacidad. Estos datos se utilizan para procesar pagos, generar recibos de transacciones, detectar fraudes y mantener registros. Si deseas obtener más información sobre los datos de información personal que recibimos, los proveedores de terceros en los que confiamos y durante cuánto tiempo conservamos tus datos, consulta nuestro Aviso de Privacidad de Sitios Web, Comunicaciones y Cookies.

¿Cómo puedo obtener un recibo comercial?

¿Mí donación es segura?

Sí, utilizamos tecnología SSL estándar de la industria para mantener segura tu información. Nos asociamos con Stripe, el procesador de pagos establecido en la industria en el que confían algunas de las empresas más grandes del mundo. Tu información financiera confidencial nunca toca nuestros servidores. Enviamos todos los datos directamente a los servidores compatibles con PCI de Stripe a través de SSL. Entendemos que tu privacidad es muy importante. Para obtener información completa, consulta la Política de privacidad de Mozilla.

Can I request a refund?

Your donation may be eligible for a refund. You must contact us within 15 days of payment date. If you believe this payment was made without your authorization, please contact us immediately. Donations made via ACH or SEPA direct debit are ineligible for refunds. Due to the nature of these transactions our policy prioritizes minimizing refund fraud. We appreciate your understanding. If you need assistance, please contact us.

Are there additional fees added to my donation?

We do not collect any additional fees or taxes. When you donate in your local currency you are not charged a conversion fee by your credit card. You can choose to also cover the payment processing transaction costs. This is completely voluntary and you may opt in or out using the checkbox on our donation form. Our organization is based in the United States. We encourage donors to research any additional external taxes or fees that may be applied by regulators such as your bank or tax authority.

What do the transaction costs cover?

When you opt to cover our payment transaction costs, you're covering both our payment processing and donation platform fees. The costs associated with our robust online donation system allows us to continue scaling sustainably as our supporter-base grows. Our donation platform and payment processor partners reduce internal costs associated with maintaining our own system from scratch. Our partners ensure we can accept a wide range of currencies/payment methods and remain PCI compliant in all of the countries that we accept gifts from. The transaction costs you may choose to cover are based on an estimate of our overall costs. Due to many factors actual costs may fluctuate.

¿Por qué las donaciones únicas aparecen como recurrentes en los mandatos SEPA?

Al realizar una donación única a través de domiciliación bancaria SEPA, es posible que notes una mención de transacciones recurrentes. Esto se debe a que nuestro procesador de pagos, Stripe, solo admite transacciones recurrentes para este tipo de pago. Sin embargo, independientemente de esto, solo te cobraremos una vez y no realizaremos más pagos en tu cuenta sin tu autorización. Tras el mandato, recibirás un recibo oficial de donación que reflejará claramente la donación única.

¿Puedo donar con criptomonedas?

No. Actualmente no aceptamos donaciones en criptomonedas.

¿Cómo se utilizará mi donación?

Thunderbird is the leading open source email and productivity app that is free for business and personal use. Your gift helps ensure it stays that way, and supports ongoing development.
