2.1 Providing and Improving Our ServicesWe use the collected information to:• Deliver and enhance the app's functionalities and features.• Personalize your experience by tailoring content and event suggestions based on your preferences and behavior.• Communicate with you about updates, changes, or relevant events.• Analyze usage data to improve the app and optimize user experience.• Monitor app performance, identify and resolve stability issues, and ensure a smooth user experience.
2.2 Finding Friends From Your ContactsIf you choose to find friends from your contacts, the app creates a one-way fingerprint (a SHA-256 hash) of the phone numbers and email addresses in your address book, on your device, and compares those fingerprints with the people already on Jamr. Only the fingerprints are sent. We do not store your contacts, we do not keep the fingerprints after the comparison, and nobody in your address book is contacted.To let friends find you the same way, you can add your own phone number in your profile or during onboarding. The number itself never leaves your device: we store only its fingerprint, which cannot be turned back into your number, and you can remove it at any time in Edit Profile.Both are optional. The app explains this before your phone asks for permission, and declining changes nothing else about how Jamr works.
2.3 Community InsightsWe combine data from many users into statistics, for example which genres are popular in a city. Venues, artists and festivals on Jamr can see such statistics about their own followers, for example "38% of your followers like indie". These statistics never show who you are: we only show them for groups of at least 25 followers, a group within them only when it has at least 10 people, and we round the figures. The legal basis is our legitimate interest in helping the live music scene; you have the right to object.
2.4 Legal BasisWe process your data in compliance with the General Data Protection Regulation (GDPR). For each purpose, this is the legal basis we rely on:• Your account and the app itself: Creating your account, your profile, the events and artists you save or follow, friends, event suggestions, and payments if you buy something. We need this data to provide the service you signed up for (performance of a contract, Article 6(1)(b) GDPR).• Sharing your details with a venue or artist you chose: Only with your consent (Article 6(1)(a) GDPR), per venue or artist and per item, and you can withdraw it at any time.• Using your device location, finding friends from your contacts, sharing your location with friends and push notifications: Only when you turn them on. The legal basis is your consent (Article 6(1)(a) GDPR), and you can switch each of them off at any time in the app or in your device settings.• Usage statistics, error reports, security and aggregated insights: To keep the app working, secure and improving. The legal basis is our legitimate interest (Article 6(1)(f) GDPR). You have the right to object to this.• Legal obligations: For example keeping payment records for tax purposes (Article 6(1)(c) GDPR).
2.5 Sharing With Venues and Artists You ChooseWhen you follow a venue or an artist, we may ask whether you want to share details with them. You choose per venue or artist, and per item: your name, your email address, and your music taste. Nothing is shared unless you turn it on, and following works the same either way. The legal basis is your consent.For a venue, your music taste means the genres we think you like, plus the artists you follow who play or have played at that venue. For an artist, your music taste means the genres we think you like.You can also make this choice for a venue or artist that does not have its own account on Jamr yet. It only takes effect once someone has claimed that profile and we have checked the claim. If that has not happened within 24 months, or you stop following the venue or artist, your choice lapses and nothing is shared.The venue or artist can see the details you shared in its Jamr account and can download them, to email you about its shows and news. From the moment the venue or artist can see them, it is responsible for how it uses your details, as a separate controller. We require venues and artists to use them only for their own programme, never to sell or pass them on, to include an unsubscribe link in every email, and to remove you from their list when you withdraw.You can withdraw at any time under that venue or artist in the app. The venue or artist then no longer sees your details, and we tell them to remove you from their list. We cannot delete a copy the venue or artist has already downloaded; for that copy you can unsubscribe through the link in their emails or contact them directly. Withdrawing does not make earlier use unlawful. If you delete your Jamr account, all your sharing choices are withdrawn and the venues and artists are told.We keep a record of what you agreed to, and when, for as long as the sharing is on and up to two years after you withdraw, so we can show what you agreed to.The same will apply to festivals once they can receive details; we will update this policy before that happens.
