The Welcome to Web3 website is an educational guide. Its 28 guide chapters do not require an account and do not collect names, email addresses or wallet details.
Integrated Web3 Knowledge Quiz
The quiz is available within welcometoweb3.com/quiz/. When you participate voluntarily, the information required to store and manage your result is processed.
This includes your name, email address, selected language, quiz level, answers, score, percentage, result level, consent, technical browser identifier and submission date and time.
Quiz results are stored in the secured Cloudflare D1 database web3-quiz-results. They are not used for advertising tracking.
When you voluntarily submit a review, the selected star rating, optional comment, language and review time are also stored. Reviews are visible only in the secured admin dashboard and are not published automatically.
Why is this information stored?
To register your quiz result, operate the educational quiz, and retrieve or delete results when requested.

Technical information

DARA Updates and call summaries
For this separate section we collect your last name, first name, email address, Telegram username and chosen language. The email address is optional contact information and is not verified during registration. After activating @DaraUpdatesBot we also store your Telegram user ID, notification preference, registration time and consent time. Telegram processes bot messages under its own privacy policy.
We use this information to provide access to summaries, personal sign-in links and notifications in your chosen language. Data is stored with Cloudflare. An essential secure session cookie keeps you signed in for up to 30 days. Sign-in links are single-use and valid for 15 minutes. Connecting Telegram and activating the bot is required to read the summaries. Notifications are enabled after activation. Ask PMJ to unsubscribe from updates or delete your information through the contact below.
Smarter with CRYPTO — Telegram Mini App
When you open the Mini App through @PMJSmarterWithCRYPTObot, we use your verified Telegram user ID to create a private profile automatically and retrieve your progress. We do not copy your Telegram name, username or profile photo. You choose your Avatar name, avatar or photo and language. Reading progress, answers, one-time article results, points, badges, first observed app visit, last-activity time, first and last active calendar day in Bangkok time, channel membership checks and invitations are stored in Cloudflare D1.
Only the administrator can view your Avatar name, reading progress, completed article quizzes, points, badges and limited usage summary in a protected overview, including when you are not on the public leaderboard. This helps administer the learning space and count usage. A first observed visit does not reconstruct an unknown historical first visit. Last activity is updated with up to five minutes between records. No full click history is kept and the overview does not show Telegram IDs.
The leaderboard checkbox is selected at first sign-in and can be cleared before saving. Leaving it selected gives permission to display your chosen Avatar name, image and points on the leaderboard and, if you reach the top 3, within the same Crypto Flash image in the Telegram channel. You can change this later through your profile photo. Turning it off hides your profile in the app; previously published channel images remain visible. Your Telegram ID and personal standing are not published.
The Mini App uses an essential sign-in session lasting up to 24 hours. Unsubmitted answers may remain on your device until you submit them or clear local storage. The Mini App contains no advertising trackers or cross-site tracking. No location or device data are collected for the limited usage summary. Your profile, progress and usage summary remain stored until you request deletion from PMJ on Telegram, using the same Telegram account you use to participate. Telegram processes use of its own app under its own privacy policy. Website quiz scores do not count for now; points currently have no redemption function or promised monetary value.
New participants who first start the bot after activation may receive up to two reminders after 24 and 72 hours in their chosen language while their profile or first two article quizzes remain incomplete. We store the first verified bot-start time and delivery outcome for this purpose. The button opens the appropriate next step based on your current progress. Existing participants are not enrolled retrospectively. A reminder does not award extra points. Only confirmed deliveries appear in the protected admin overview. You can stop messages by blocking the bot in Telegram or asking PMJ to unsubscribe you; deletion requests also cover reminder records.
During the temporary article-sharing trial, we record which article you prepare using the share button, its language and whether Telegram reports that you shared it. A personal code lets us measure whether new participants then save a profile and complete a first article quiz. We do not receive a list of the chats or people you share with. The administrator sees totals by language. The existing reward of 2 points per newly saved profile is unchanged.
Participants with at least two submitted article quizzes may receive one return reminder after seven days without active app use, in their chosen language. The delay is based on the last recorded active app use, not incoming messages or passive background refreshes. The reminder is not repeated weekly while you remain inactive. A new active visit can start a new seven-day inactivity period. We store the relevant activity timestamp and delivery status; this does not change your points or badges.
