Terms of Use of the "WELCOME20" voucher promotion in DB Navigator

1. Scope and vendor
   These Terms of Use govern the redemption of promotional vouchers from the "WELCOME20" welcome campaign (hereinafter "voucher") for mobility services provided by TIER Mobility SE (Dott) that are booked in the DB Navigator app. The Vendor of the vouchers is DB Fernverkehr AG, Europa-Allee 78-84, 60486 Frankfurt, Germany.

    

2. Promotional period
   The voucher promotion starts on 23 June 2026. Vouchers are valid from activation until 31 August 2026. After this period, the voucher expires without replacement.

    

3. Authorised participants
   The voucher can be used by anyone who has an active private DB customer account in which data authorisation for "sharing services" has been granted and a valid means of payment for booking sharing services has been stored. 

    

4. Redemption 
   The voucher can be redeemed exclusively in DB Navigator for booking mobility services from TIER Mobility SE (Dott). The voucher cannot be redeemed via other applications or platforms, or for products and offers of Deutsche Bahn AG or its affiliated companies. Only one voucher can be redeemed per booking of a mobility service from TIER Mobility SE (Dott). This voucher cannot be combined with other vouchers, BahnBonus rewards or special offers from Deutsche Bahn.

    

5. Granting of discounts
   The "WELCOME20" voucher grants a discount of 20% (twenty per cent) on the fare, which is made up of the activation fee and the price per minute, for all bookings of mobility services of TIER Mobility SE (Dott) within Germany that are made in DB Navigator during the promotional period. The discount is not granted on any additional costs or fees arising from the use of mobility services provided by TIER Mobility SE (Dott), such as service fees or fines. Once the voucher has been redeemed for the first time, the discount will be granted for an unlimited number of bookings of mobility services from TIER Mobility SE (Dott) within the promotional period. 

    

6. Misuse and exclusion
   The Vendor reserves the right to block the voucher in the DB customer account, or refuse to redeem it in the event of suspected misuse or violations of these terms of use.

    

7. Changes to the promotion
   The Vendor reserves the right to change these Terms of Use with effect for the future if this becomes necessary for valid reasons, e.g. if disruptions occur that could significantly impair the voucher promotion, provided that the change is reasonable for the users, taking due account of their interests. The Vendor will inform persons who have a corresponding voucher in their DB customer account in advance of any changes. If they do not agree with the changes, they can delete their voucher from their DB customer account. It will then no longer be possible to utilise the discount.
