Privacy Policy

NaDrumu is a marketplace for vehicles, parts and related services. It connects buyers and sellers, and users and workshops. This policy explains how the operator, Mladen Jovanović, handles personal information when you use NaDrumu. For privacy questions or requests, email nadrumu@gmail.com.

Information we may process

• Pi sign-in: your verified Pi identifier and username, and the session information needed to keep you signed in. Pi access tokens are used to verify sign-in and are not stored as login credentials.
• Profile: details you choose to enter, such as your display name, description, location and profile images.
• Listings: descriptions, item details, prices, listing images and contact details you submit.
• Favorites: the listings you save to your account.
• Workshops: workshop details, images, contact information, services, opening hours and appointment settings submitted by the workshop owner.
• Bookings: the selected workshop, service and appointment, customer contact details and booking status.
• Pi payment records: order and payment identifiers, purchased NaDrumu services, amounts, the conversion rate used, payment status, transaction references and verified service entitlements.
• Technical and security information: session cookies, IP addresses or protected identifiers, request times, device/browser information, error reports and security records where needed to operate and protect the service.
• Support: the message and relevant details you send when contacting us.

Why we use this information

We use information to provide sign-in and account features, display and manage listings, save favorites, operate workshop bookings, verify and reconcile Pi payments, provide paid NaDrumu services and respond to support or privacy requests. Technical information helps us keep the app working, prevent fraud and abuse, investigate errors and resolve disputes.

We do not sell personal data to advertisers. We do not ask for information that is unnecessary for the feature you use. Please do not submit unrelated sensitive information, passwords, wallet recovery phrases or private keys.

Public and private information

Published listings and workshop pages, including the images and contact details you choose to publish, are visible to marketplace visitors. Booking details are available to the relevant customer and workshop owner. We use access controls for account and payment records. Information may also be accessed when needed to provide support, protect the service or meet a legal obligation. Avoid putting private or sensitive information in public descriptions or images.

Location and device storage

Location lookup is optional and starts when you choose to use it and allow location access. Coordinates are sent to BigDataCloud to identify a city; NaDrumu does not store the raw coordinates from that lookup. You can select a location manually. Your browser may store preferences, local drafts and recent market estimates. On shared devices, local drafts may remain until you remove them or clear site storage.

Service providers and third parties

Infrastructure providers such as Sites and Cloudflare support hosting, storage and security. Pi Network participates in Pi sign-in and payments. Market-data providers such as CoinGecko, CoinPaprika and OKX supply price information. Location, image or font providers may receive requests when their services are used.

Optional Sentry error monitoring and PostHog analytics operate only when configured; session replay is separately controlled. Providers may process the information necessary for their part of the service. Pi Network and other third-party services have their own privacy policies when you use their services in a NaDrumu flow.

How long information is kept

Information is kept for as long as needed to provide the service, protect security, resolve disputes and meet applicable legal obligations. When information is no longer needed, it is deleted or anonymized where applicable. Some payment or security records may need to remain after a listing or account is removed. Public blockchain transaction records are outside NaDrumu's control and cannot be erased by NaDrumu.

Your privacy requests

You may request access to, correction of or deletion of your personal information where applicable. Send privacy and deletion requests to nadrumu@gmail.com. Describe the request and provide enough information to identify the relevant account or content. We may need to verify that the request concerns your information; do not send wallet recovery phrases, private keys or access tokens.

We will review your request and explain any information that must be retained for security, dispute resolution or legal obligations. Removing information from NaDrumu does not remove copies independently kept by other users or records controlled by third parties.
