Marburg Club

Terms of participation

These terms govern participation in the Marburg Club loyalty programme in the app, in the web app, with the printed loyalty card and at the counter of participating businesses.

Die deutsche Fassung ist rechtlich verbindlich. This English text is a convenience translation. In case of any discrepancy, the German version prevails — read it here.

§ 1 Operator

Marburg Club is operated by Pale Blue Dot GmbH, Alte Kasseler Straße 52, 35039 Marburg (“we”). Full operator details are in the legal notice. We run the platform: app, web app, loyalty card and the record of stamps and rewards. Rewards and offers are provided by the participating businesses (§ 7).

§ 2 Participation

  1. Natural persons aged 16 or over may take part. You confirm this yourself: when you register an account and, if you scan in the browser without an account, before your first stamp request. Whoever uses a printed card confirms it with the first use (§ 5 (1)).
  2. Participation is free. There is no obligation to buy.
  3. One account per person. Guest and card profiles that arise automatically (§ 3 (2), § 5) do not breach this.
  4. There is no entitlement to take part.

§ 3 Account, guest, conclusion of the contract

  1. Account. You sign in with a one-time code sent to your email address, with Apple or with Google. The contract is concluded when you accept these terms at registration.
  2. Guest. If you scan without an account, you accept these terms and confirm your minimum age at the scan; only then do we create a guest profile. The contract is concluded with that acceptance. Access to a guest profile depends on your browser or app: if its storage is cleared, the stamps can no longer be reached. So secure them with an email address or through Apple or Google; the guest profile then becomes an account with the same stamps. If the sign-in you pick already belongs to another account, the balances are not combined.
  3. Do not share your access details.

§ 4 Stamps

  1. The QR code at the counter changes continuously. A scan, including staff scanning your card or your code, creates a request.
  2. Only staff approval credits the stamp. The business may refuse, for example if no visit took place. A scan alone creates no entitlement.

§ 5 Printed loyalty card

  1. With a printed card you can take part without the app and without an account. These terms apply from the card's first use; the card and its card page point to them.
  2. The card is a bearer card. Whoever shows it can collect stamps and redeem rewards; whoever scans its QR code sees its balance. Keep it safe.
  3. The card does not expire. Stamps and rewards expire under § 9.
  4. Loss. With an account you block the card in the app, without one by email to datenschutz@marburg.club. A blocked card stays blocked. Stamps collected with a lost card without an account cannot be linked to a person and therefore cannot be replaced.
  5. Linking. A new, unused card can be added to any account. A card that has been used only to an account that has no stamps, visits, rewards or offers in Marburg yet. The card's balance then moves over unchanged; balances are not combined.
  6. If a card's data is deleted, on request or under § 10 (3), the card is released. It can then be used again, empty; the previous balance has lapsed.

§ 6 Rewards and offers

  1. A programme sets the number of stamps, the reward and the businesses. You see all of it in the app or on the card page.
  2. A programme may repeat or lead to a follow-up programme.
  3. To redeem, show your code or card at the counter; only staff confirmation redeems. Redemption uses up the stamps it needs.
  4. Promotional offers, including discounts, may be limited: by quantity, per account, in time or to certain email domains. Reservations may expire. The conditions are shown with the offer.
  5. Stamps and rewards are not paid out in cash.

§ 7 Who owes rewards and offers

  1. The business named owes them and is your contracting party for them. We do not promise them as our own performance, even where we advertise them in the app and on the website.
  2. If a business refuses a reward, we confirm your balance on request. Report the case to info@palebluedot.de.
  3. Our liability under § 12 is unaffected.

§ 8 When a business leaves

  1. Stamps belong to the programme, not to the business. They stay redeemable at every other business of the same programme.
  2. If the programme runs nowhere else, we make sure collected stamps can be redeemed until they would normally expire, if necessary for an equivalent reward at another participating business.
  3. If a programme ends altogether, we announce in the app a reasonable period in which earned rewards can still be redeemed.

§ 9 Expiry

  1. A programme may set a validity for stamps and a redemption period for rewards. They are shown in the app; if none is shown, nothing expires.
  2. Expiring stamps never take away a reward already earned.
  3. New or shortened periods apply only to stamps issued and rewards earned afterwards.

§ 10 Misuse and termination

  1. In particular, it is not allowed to copy, pass on or tamper with the counter codes, to collect stamps without a visit, to use automated tools or to hold several accounts to get round the rules. Where there are objective indications, we may, after hearing you, remove individual stamps, block the account and, for serious breaches, end participation.
  2. You may terminate at any time by deleting your account (app: Profile → Account; otherwise by email). We may terminate with four weeks' notice, or without notice for good cause. If we terminate without good cause, earned rewards stay redeemable for another four weeks.
  3. Inactivity. An account without sign-in and without a visit for 24 months, and a guest or card profile without a visit for 12 months, is deleted. Unredeemed stamps and rewards lapse with it.

§ 11 Availability, wallet

We aim for uninterrupted operation but do not owe constant availability. A wallet card does not always show the current balance. After linking a printed card you need to add an Apple Wallet card again.

§ 12 Liability

We are liable under the statutory provisions, in particular for running the platform and recording your stamps correctly.

§ 13 Changes

  1. We present changes to these terms in the app. They apply to you only once you accept them. Until then you cannot continue to use the app; if you decline, you may terminate, and earned rewards stay redeemable for four weeks. Anyone who scans as a guest in the browser accepts the current version at the scan.
  2. We may change the participating businesses and the content of programmes for an objective reason, such as businesses joining or leaving or changes in the law. Earned rewards are not affected.

§ 14 Law, dispute resolution

  1. German law applies. Mandatory consumer protection of the country where you habitually live is unaffected.
  2. We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.
  3. There is no right of withdrawal, because you provide only personal data that we process exclusively to run the programme (§ 312 (1a) sentence 2 BGB). Termination under § 10 (2) is open to you at any time.
  4. If a provision is invalid, the others remain valid.
