RK Tech Works Privacy Policy

Date of this Version: December 8, 2022

At RK Tech Works, we are committed to protecting your privacy. We do not sell or rent information about our customers or visitors. All information provided to us remains confidential, except as required by law or to comply with a court order or other legal process.

We will not collect any personal information about individuals except when specifically and knowingly provided by such individuals. Examples of such information are: email address and phone number. We will not disseminate this information to any outside parties outside of RK Tech Works, and our agents for any payment processing, ID verification or compliance verification. None of our applications ask for credit card numbers.

We do not sell or rent any information for an external entity's direct marketing purposes.

We may share non-personal aggregate, or summary, information regarding our customers with partners or other third parties, but we do not sell or share any information at the individual customer level.

Our web server collects access logs containing click-stream data and HTTP protocol elements, including IP addresses. We collect this data for the purpose of site administration, completing the user's current activity and research and development. This data is only used internally.

We do not collect HTTP cookies, except as noted below.

Product-specific privacy

The applications and services developed by RK Tech Works are designed around privacy and collecting the minimum amount of information on its users.

ID Pocket

As a decentralized application, there is no central database of all users. All data that you create is stored locally in your app. We can glean information from the app stores as to how many people have downloaded the app and currently use it, but we gather no personal information from our users.

If you choose to use more of the functions than storing/displaying paper-based credentials, you can connect an Ethereum account to the app. The app then stores your Ethereum address, private recovery phrase and an encryption key that is derived from a message that is signed using the Ethereum account.

If you choose to backup your data to our cloud storage service, the filename of the backup file contains your Ethereum address, along with a unique character string based on your encryption key. The backup files are encrypted with your encryption key, so you are the only person that can decrypt it. As an extra privacy measure, to thwart anyone who knows your Ethereum address from downloading your backup file (even though it's encrypted), they would also need to know the extra character string, which has over 4 billion possibilities. If you no longer want your backup file, you can request that we delete it from the cloud storage service.

If you use our URL Shortener service when generating QR Codes, we store a record in a remote database containing the short code, the long URL, along with your Ethereum address. These records are regularly deleted after they expire.

If you purchase any additional services, such as identity verification services, we (or our service provider) may collect personal information to provide the service. All such information is deleted or redacted as soon as the service has been provided.


As an email alias and forwarding service, we are very focused on privacy. We collect the bare minimum information about you, and only track usage so we can provide statistics for you and us.

We collect your email address, as we need it to forward emails to you. We also use your email address to send you service-related messages such as account verification, payment reminders and when we discard an incoming email due to a high level of inappropriate words.

We collect a username, although that can be any combination of letters and numbers, so long as it's unique within the system.

We collect a decentralized identifier (DID), which is an account identifier that your digital wallet provides. Based on the wallet used, it may be unique for this service, or it may the the Ethereum address used in the wallet. This identifier is hashed (one-way encrypted), so the system cannot decrypt it.

We store a list of the email aliases that you've told us to block, so that we can properly block them. We do not store any list of alias names that you use.

We do not use or store passwords.

We track the number of emails received, blocked or sent by user. We do not tag each log entry with a timestamp, but rather keep a count of each by user and by day.

When you login to the service website, we store two cookies, one to track your login session and one to control against cross-site request forgery attacks. No personal information is stored in these cookies.

If you pay for this service using a digital currency, we'll store a randomized transaction reference number only until the transaction is confirmed on the blockchain, then it is removed. Your choice of digital currency can increase your privacy during payment.

Website and email server log files are deleted as soon as operationally possible.

Wine Flavs

We collect and store an email address and password for each user, so that they can login to the service. Optionally, the user can choose to store their ZIP Code to aid in finding wine retailers close to them. The passwords are stored using one-way encryption.

If you no longer want an account on this app, you can delete your account, and all associated data, by pressing the button on the profile page.

We collect HTTP cookies once a user logs in to track the session to ensure that a valid user is accessing the pages.

We store your saved flavor profiles and your favorite wines. We only use this data for summary-level analytics.

Deleting Your Personal Data

You have the right to delete or request that We assist in deleting the Personal Data that We have collected about You.

Our services may give You the ability to delete certain information about you from within the service.

You may update, amend, or delete Your information at any time by signing in to your account, if you have one, and visiting the account settings section that allows you to manage your personal information. You may also contact us to request access to, correct, or delete any personal information that You have provided to us.

Please note, however, that we may need to retain certain information when we have a legal obligation or lawful basis to do so.
