Onko lahja verotuksessa vähennyskelpoinen?

Gifts to Thunderbird are not tax-deductible as charitable gifts, but are greatly appreciated. Giving to Thunderbird supports the development of our leading open source cross-platform email and calendaring client, free for business and personal use. Your gift will help ensure it stays that way, and will support future development.

How can I get a business receipt?

When you donate via our online form, simply check the box 'Donate as an Organization' and include your company name. The receipt you receive to the email address used to make your contribution will include your business information.

Onko lahjoittaminen turvallista?

Yes, we use industry-standard SSL technology to keep your information secure. We partner with Stripe, the industry's established payment processor trusted by some of the world's largest companies. Your sensitive financial information never touches our servers. We send all data directly to Stripe's PCI-compliant servers through SSL. We understand that your privacy is very important. For complete information please refer to the Mozilla Privacy Policy.

Can I request a refund?

Your donation may be eligible for a refund. You must contact us within 15 days after the date of the donation. If you believe this donation 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 sincerely appreciate your understanding. If you have any further questions, please contact us.

Are there additional fees on 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. Optionally, you can choose to cover our transaction costs on your donation. 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 are your transaction costs on donations?

When you opt to cover our transaction costs, you're covering both our processing and donation platform costs. 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 donors may choose to cover are based on an estimate of our overall costs. Due to many factors actual costs may fluctuate.

Why do one-time donations appear as recurring in the SEPA mandates?

When making a one-time gift through SEPA direct debit, you may notice a mention of recurrent transactions. This is because our payment processor Stripe only supports recurring transactions for this type of payment. Regardless of this, we will only charge you once and we will not make any further payments on your account without your authorization. Following the mandate, you will receive an official donation receipt that will clearly reflect the one-time donation.

Voinko lahjoittaa kryptovaluuttoja?

Ei. Emme tällä hetkellä ota vastaan kryptovaluuttalahjoituksia.
