Privacy Policy

What Bloxstack collects, why, who else sees it, and how to get it deleted. Short version: less than you would expect, and none of it is sold.

Effective 8 August 2026Last updated 8 August 2026

This policy explains how Bloxstack ("Bloxstack", "we", "us") handles personal data on bloxstack.app. It forms part of our Terms of Service.

A2Z Labs Inc., a Delaware C corporation, operates Bloxstack and is the controller of the data described here. For anything in this document, including a request to access or delete your data, write to [email protected].

We do not sell your personal data, we do not share it with advertisers, and we run no advertising or analytics trackers on the site.

1.Scope#

1.1This policy covers the Bloxstack website and the services we operate on it, for members and for signed-out visitors.

1.2It does not cover Roblox. Your Roblox account is governed by Roblox’s Privacy Policy, and Roblox decides what it does and does not tell us about you. It also does not cover a third-party site you reach from a link on Bloxstack, including a link another member posts.

2.What we collect#

2.1Everything we hold about you falls into one of these rows.

DataWhere it comes from
Roblox user id, username, display name, avatar imageRoblox, at sign-in, from the `openid profile` scope you approve. The user id is the permanent anchor of your account; the rest refreshes when you sign in again.
Roblox access and refresh tokensRoblox, at sign-in. Held encrypted so we can refresh your linked identity. See §11.
Your profileYou. Handle, display name, headline, bio, crafts, rates, availability, showcase, banner, theme, and layout choices.
What you publishYou. Listings, briefs, applications, forum posts, comments, reviews, and endorsements.
Private messagesYou and the members you talk to. Messaging is an adult-only surface; conversations are stored so both sides can read them.
Deal recordsYou and the other member. What was agreed, what was delivered, and the state of the engagement.
SessionsAutomatically, when you sign in: a session record with its IP address, browser user agent, and timestamps. You can see and revoke your active sessions in Settings.
Abuse and rate-limit countersAutomatically. Keyed by a keyed hash of the IP address rather than the address itself, so the counter works without our storing a readable IP for it.
Payment recordsStripe, when you buy or sell. Customer, checkout, subscription, and connected-account identifiers, plus what was bought and its state. We never receive or store your card number.
Recovery email addressYou, and only if you choose to add one in Settings. A Roblox sign-in gives us no email, so an account created that way starts with a placeholder address that cannot receive mail.
Email address, for the founding cohortYou, if you sign in at /waitlist with an emailed link. Or Google, if you sign in with Google, in which case Google also tells us your name, your profile picture, and that the address is verified. See §3.5.
Your waitlist recordYour email address, the name you gave, when you joined, whether your account has claimed the spot, and whether you have unsubscribed. It includes people who joined the earlier Bloxstack waitlist before this version of the site existed.
Announcement mail recordsAutomatically, one row per announcement we send you, so the same message is never sent twice. It records the address it went to, whether it was delivered, and any error.
Notification preferencesYou. Which notifications you want, and whether you want them by email.
Invite attributionA first-party cookie set when you arrive through another member’s invite link, so their invite count is correct after you sign up.
Reports, appeals, and support messagesYou, or the member reporting something, along with our moderation notes about the outcome.
Server logsAutomatically. Ordinary web-server and application logs used to keep the site running and to investigate faults and abuse.

3.What signing in gives us, and what it does not#

3.1We use Roblox as an OpenID Connect sign-in provider. When you approve Bloxstack on Roblox, we ask for two scopes and no others: `openid`, which tells us your account identifier, and `profile`, which gives us your username, display name, and avatar image.

3.2We never receive your Roblox password. We do not receive your Roblox email address, your age, your date of birth, your age bracket, your friends or followers, your inventory, your Robux balance, your presence, your private messages, or anything about the games you play.

3.3We do not write anything to your Roblox account, we cannot act on Roblox on your behalf, and we do not use the connection to read anything beyond the four fields above.

3.4You can disconnect Bloxstack from your Roblox account at any time from Roblox’s own authorised-applications settings. Doing so stops the connection; it does not by itself delete your Bloxstack account, which you can ask us to do under §10.

3.5Roblox is not the only door, and the exception is where an email address enters the picture. The founding-cohort page at /waitlist also accepts an emailed sign-in link, which gives us the address you type and nothing else, or a Google sign-in, in which case Google tells us your email address, your name, your profile picture, and that Google has verified the address. We ask Google for nothing beyond that, and we never receive your Google password. That address is what we use to match you to your waitlist spot and to send you the announcements described in §4.

4.Why we use it#

4.1We use the data in §2 for these purposes and no others.

  • To run your account: signing you in, keeping you signed in, showing your profile, and proving that your profile controls the Roblox account it names.
  • To provide the features you use: the jobs board, the marketplace, messaging, the forum, reputation, and notifications.
  • To take payments, pay sellers, and keep the records that tax and accounting law requires.
  • To keep the Service safe: rate limiting, fraud and abuse prevention, moderation, and enforcing our Terms.
  • To communicate with you about your account, a purchase, a report, or a change to these policies.
  • To email the founding cohort about the launch and about what we are building, if you are on the waitlist. Every one of those messages carries a one-click unsubscribe link that works without signing in, and using it stops them for good.
  • To understand, in aggregate, how the product is used so we can improve it. We do this from our own data; we run no third-party analytics.
  • To comply with the law, and to respond to a lawful, valid request from an authority.

4.2Where the GDPR or a similar law applies to you, our legal bases are: performance of our contract with you (running your account, deals, and purchases); our legitimate interests (security, abuse prevention, keeping invite attribution honest, and improving the product); compliance with a legal obligation (tax, accounting, and lawful requests); and your consent, where we ask for it, which today means optional email notifications and the founding-cohort announcements and nothing else. Where we rely on legitimate interests, you may object under §10, and you can withdraw consent to the announcements from any one of them without contacting us at all.

5.Cookies and browser storage#

5.1We use two cookies, both first-party, both strictly necessary for something you asked for.

CookieWhat it does
Session cookieKeeps you signed in. Set when you sign in, cleared when you sign out, and revocable from Settings.
Invite cookie (`bsref`)Set only if you arrive through a member’s invite link, so their invite is credited after you sign up through Roblox. It is readable only by our server, holds nothing but the referring member’s code, and expires after 30 days.

5.2There are no advertising cookies, no analytics cookies, no third-party cookies, and no tracking pixels on Bloxstack. Nothing follows you to another site.

5.3Your browser also stores a few preferences locally: your light or dark theme, which dismissible banners you have dismissed, and unsent drafts of a listing or a brief so a closed tab does not lose your work. That storage stays in your browser and is never sent to us. Clearing your site data removes it.

6.Who else sees your data#

6.1Other members see what you publish. Your profile, listings, briefs, forum posts, reviews, and endorsements are public to anyone on the internet and are indexed by search engines. Your private messages are visible to the members in the conversation, and to our moderators when a conversation is reported.

6.2Beyond that, we share data only with the service providers below, each of which processes it on our instructions and for the stated purpose only.

ProviderWhat it handles
Roblox CorporationSign-in. Roblox knows you authorised Bloxstack. We send Roblox nothing about your activity here.
GoogleSign-in, and only for the members who choose the Google door on the waitlist page. Google knows you signed in to Bloxstack. We send Google nothing about your activity here.
StripeAll card payments, subscriptions, seller onboarding, and payouts, plus the identity and age verification required to receive money. Card details go to Stripe, never to us.
Cloudflare R2Object storage for images you upload. Uploads and downloads go directly between your browser and storage using short-lived signed links; the buckets are not public.
ResendDelivers the email we send: sign-in links, the small number of transactional messages, and the founding-cohort announcements. It receives the address the message is going to.
UpstashHolds the abuse and rate-limit counters described in §2.
OVHcloudHosts the application and the database, on dedicated hardware in Beauharnois, Canada.

6.3We will also disclose data where the law requires it, where it is necessary to establish or defend a legal claim, or where we believe in good faith that disclosure is needed to prevent serious harm to someone. Where we are permitted to tell you about such a request, we will.

6.4If Bloxstack is ever acquired or merged, your data may transfer to the successor, which would remain bound by this policy until you are given notice of a replacement.

6.5We do not sell personal data, and we do not "share" it for cross-context behavioural advertising as those terms are used in United States state privacy laws.

7.International transfers#

7.1Bloxstack is operated from servers in Canada, and the providers in §6 operate in Canada, the United States, and the European Union. Using the Service therefore involves transferring your data across borders.

7.2Where a transfer is subject to the GDPR or United Kingdom data protection law, we rely on the European Commission’s Standard Contractual Clauses (with the UK Addendum where applicable) or on an adequacy decision, as offered by the provider concerned.

8.How long we keep it#

8.1Your account, profile, and published content are kept while your account exists.

DataRetention
Account, profile, posts, listings, messagesUntil you delete them, or until your account is deleted. Erased from live systems within 30 days.
SessionsUntil they expire or you revoke them.
Waitlist record and announcement-mail rowsKept while the founding cohort is live. Deleting your account releases the claim on your waitlist spot but does not erase the waitlist row, because the row predates the account. Say so in your request and we will take the address off the list entirely.
Rate-limit countersMinutes to hours. They expire on their own.
Payment and transaction recordsKept for as long as tax and accounting law requires, typically seven years, even after account deletion. Stripe keeps its own records under its own policy.
Moderation recordsKept while needed to enforce a suspension or ban and to handle an appeal or a legal claim.
Server logsRotated on a short cycle in the ordinary course.

8.2Encrypted backups may still contain deleted data until they rotate out in the ordinary course. We do not use a backup to restore something you asked us to delete.

9.Children#

9.1Bloxstack is a professional network for people who make things, and it is not directed to children under 13. You must be at least 13 to hold an account.

9.2If we learn that an account belongs to someone under 13, we delete the account and the data attached to it. A parent or guardian who believes a child under 13 has given us data should write to [email protected] and we will act on it promptly.

9.3Roblox does not tell third-party applications how old a user is, and we deliberately do not ask for that signal. Nowhere in the Service do we ask you for your date of birth. We hold no birthdate, no age, and no age bracket for you, which is why the rest of this section is written the way it is.

9.4Because we hold no age data, we cannot verify age, and we do not pretend to. The Terms restrict private messaging, hiring, selling, advertising, and anything involving money to members who are 18 or older, but today that is a rule enforced by moderators acting on reports, not an automated gate. There is one exception: Stripe runs a real identity and age check on anyone who receives money. If a parent has been told that Bloxstack technically separates adults from minors, this clause is the correction.

9.5If a member tells us they are under 18, or we otherwise learn it, we act on it by hand under the Terms: closing adult surfaces to that account and removing an adult who has sought private contact with a minor. When an age-verification provider is connected and the automatic band becomes active, we will update this policy before it takes effect, and the effective date at the top will tell you it changed.

9.6Because public pages are public, the safest posture for a younger member is the ordinary one: publish your work, never your contact details.

10.Your rights#

10.1Depending on where you live, you have some or all of these rights: to know what we hold about you and get a copy; to correct it; to have it deleted; to restrict or object to how we use it; to receive it in a portable format; and to withdraw a consent you gave us. Exercising a right never costs you anything and never worsens the service you get.

10.2Some of this is self-service today: your profile is editable in Settings, you can revoke sessions there, you can turn off email notifications there, and you can delete individual posts and listings yourself.

10.3A one-click account deletion is not built yet, and we would rather say so than let you find out. Until it ships, email [email protected] or ask through the support desk and a person will erase your account and the content attached to it within 30 days, keeping only what §8 says we must. The same address handles access, correction, portability, and objection requests, on the same timeline.

10.4We verify a request by requiring it to come from your signed-in account or from the recovery address on file. The alternative, handing your data to whoever asks, is worse than the friction.

10.5If you are in the European Economic Area or the United Kingdom you may complain to your local supervisory authority. If you are in California you may exercise your rights through an authorised agent. We would rather hear from you first, and usually resolve it faster.

11.Security#

11.1The site is served over HTTPS only. Session cookies are HTTP-only, and sensitive actions require a recent sign-in before they will run.

11.2The Roblox tokens we hold are encrypted before they are written, with the key held outside the database, so a database copy alone does not yield a usable token. We do not store passwords for the Service at all, because there are none.

11.3You can add two-factor authentication and review your active sessions in Settings. Because a Bloxstack profile is reached through the account that signs into it, securing that account (your Roblox account, or the Google account or mailbox you used at /waitlist) is the most important thing you can do for your Bloxstack account.

11.4Uploaded files live in private storage and are reachable only through short-lived signed links. No storage bucket is publicly listable.

11.5No system is perfectly secure. If we become aware of a breach affecting your personal data we will notify you and the relevant authorities as the law requires. If you find a vulnerability, report it to [email protected] rather than exploiting it, and we will not pursue you for a good-faith report.

12.Automated decisions#

12.1Ordering on Bloxstack is automated and, at the moment, plain: search results are ranked by how well the text of your profile matches the query, then by recency; directories and listings are ordered by recency or by the sort you pick. Endorsements and delivery record are shown on a profile, but they do not currently move you up a results page. Ordering affects visibility, not rights, and it is not a decision with a legal or similarly significant effect on you.

12.2Enforcement decisions that do affect your account (removal, suspension, termination) are made or confirmed by a person, and are appealable under the Terms.

13.Changes to this policy#

13.1We update this policy when what we do changes. The effective date at the top always tells you which version is current.

13.2If a change materially affects how we use data we already hold, we will give notice before it takes effect, and will ask for consent where the law requires it.

14.Contact#

14.1Privacy questions, data requests, and anything else in this document: [email protected].

14.2Account problems, reports, and appeals are handled faster through the support desk, by the same people.
