2. Product Overview
B3dtime is a sleep-to-earn application built on VeBetterDAO in collaboration with Goatz Club NFT and Efebia. It helps users monitor, improve, and gamify their sleep habits by rewarding them with $B3TR tokens for recorded night-time sleep. The reward model encourages healthy sleep patterns, particularly durations around 7–8 hours, as recommended for most adults.

7. Data Security
We implement technical and organizational safeguards such as:
End-to-end encryption of data in transit

Legal Basis for Processing:
Performance of a contract (i.e., providing the dApp and issuing rewards)
Compliance with legal obligations
Legitimate interests (fraud prevention, product improvement)
Retention:
We store off-chain data (e.g., usage logs) for up to 12 months after last activity. However, all blockchain-based data is stored permanently and cannot be deleted.
Data Transfers:
We may transfer data outside the EEA. Where we do, we rely on appropriate safeguards, such as:

Please note that data recorded on the blockchain (e.g., wallet address and session reward transactions) is public, immutable, and cannot be modified or deleted due to the technical architecture of blockchain networks. However, if you'd like to dissociate your future activity from past data, you can do so by creating a new wallet address.
To exercise your rights or make a request, please contact us (see Section 10). We may request information to verify your identity.
