Privacy
Introduction
This Privacy Policy is part of the Stack App Terms of Service at stack.so/privacy . All terms, conditions, and terminology are consistent with the Terms of Service, and the Terms of Service are incorporated into this document by reference. This policy governs the use of the Stack website at stack.so and the associated tools and services. Collectively, the website and the associated tools and services are referred to as the “Services” in these terms. The operator may offer other products and services. In addition to the website and the associated tools and services, the Services include:
The Services do not include outside websites or platforms which may be linked or interconnected to the Services. Such outside platforms may have their own terms of service, which control for all transactions on such platforms. These outside platforms may include, but are not limited to:
The Blockchain
Blockchain technology, also known as distributed ledger technology (or simply ‘DLT’), is at the core of our business. Blockchains are decentralized and made up of digitally recorded data in a chain of packages called ‘blocks’. The manner in which these blocks are linked is chronological, meaning that the data is very difficult to alter once recorded. Since the ledger may be distributed all over the world (across several ‘nodes’ which usually replicate the ledger) this means there is no single person making decisions or otherwise administering the system (such as an operator of a cloud computing system), and that there is no centralized place where it is located either.
This means that by design, a blockchain’s records cannot be changed or deleted and is said to be ‘immutable’. This may affect your ability to exercise your rights such as your right to erasure (‘right to be forgotten’), or your rights to object or restrict processing, of your personal data. Data on the blockchain can’t be erased or changed. Although smart contracts may be used to revoke certain access rights, and some content may be made invisible to others, it is not deleted. In certain circumstances, in order to comply with our contractual obligations to you (such as delivery of tokens) it will be necessary to write certain personal data, such as your wallet address, onto the blockchain; this requires you to execute such transactions using your wallet’s private key.
In most cases ultimate decisions to (i) transact on the blockchain using your wallet address, as well as (ii) share the public key relating to your wallet address with anyone (including us) rests with you.
If you want to ensure your privacy rights are not affected in any way, you should not transact on blockchains as certain rights may not be fully available or exercisable by you or us due to the technological infrastructure of the blockchain. The blockchain is available to the public and any personal data shared on the blockchain will become publicly available.
