This policy describes how Schemdeck handles information today. Optional accounts provide a private Workbench, plus account and billing management. Schemdeck offers a Free plan and a paid Pro subscription; Schemdeck does not receive or store payment card details — see “Payments” below.
At a glance
A plain-language summary — it doesn’t replace the full policy below, where every point here is explained in more detail.
- No advertising or behavioral tracking cookies, and no third-party advertising trackers.
- Aggregate, anonymous website traffic and performance analytics (Vercel Web Analytics and Speed Insights) — never tied to your identity or account, and never used to personalize what you see.
- Your Workbench — profile, preferences, and builds — is private. Nothing about it is public.
- An optional “Yes — this worked” button appears after you complete a build. Only if you press it does Schemdeck store one success report for your account; the public sees just a total per Blueprint, never who reported it.
- A build is only recorded as started the first time you deliberately move forward through its Manual — simply opening or browsing a Blueprint adds nothing to your account.
- Personalized suggestions use only what you deliberately provide — build preferences and saved, started, or completed builds — never passive browsing activity.
- Schemdeck does not sell personal information.
- You can usually delete your account and its data yourself from Account settings — support handles it if a billing record blocks self-service deletion.
Information you provide
If you email Schemdeck, Schemdeck receives what is in that message, which typically includes your email address, your name if you include it, and the contents of the message itself.
If you create an account, the authentication provider (Supabase) stores your email address, a securely hashed password, and standard authentication records such as sign-in timestamps. Schemdeck uses this to sign you in and to associate any billing with your account.
Signed-in accounts also have a private workbench. There, you may optionally add a display name, a profile picture, a short bio, and build preferences (categories you’re interested in, a comfort level, and a typical project budget). All of this is optional — an account works without it. Schemdeck’s systems also support a private inventory of hardware or parts you own; this is not currently offered as an editable feature in the product, but any inventory data already stored on an account (from before this feature was paused, or from testing) remains private and is handled under this same policy.
New to Tech / Tech References (/learn) requires an account. The only thing your account stores about it is whether you have finished or skipped the first-time New to Tech introduction — a single yes/no flag, so you are not shown it again on another device. Schemdeck does not record which topics you read, which reference entries you opened, or what you searched for there.
The workbench also records the Blueprints you deliberately act on: which ones you save for later, which ones you are building, which ones you mark complete (and when), and the page you last had open in a Blueprint you are building, so you can pick it up again on another device. Merely opening or browsing a Blueprint never creates any of this — a build is only recorded as started the first time you deliberately move forward through its Manual (using its Start/Next page controls), at which point Schemdeck begins saving your in-progress status and where you left off. Marking a build complete is always a separate, deliberate action on the Manual’s final page — reaching the last page on its own does not complete anything. Schemdeck does not record, in your account, the pages you visit, the searches you run, or the catalog filters you click. (Separate, aggregate, anonymous traffic analytics exist site-wide and are described under “Cookies and tracking” below; they are never linked to your account, never used to personalize anything, and are entirely separate from the account-specific build records described here.)
Schemdeck uses your stated preferences and your saved, started, and completed builds to personalize what it suggests to you — for example, proposing a project that commonly follows one you just finished. Each suggestion tells you why it is being shown. This is first-party personalization inside your own account, not advertising profiling, and no third party is involved in it.
None of this is public. There is no public profile page, no activity feed, and no shared build history: no other user can see your builds, bio, preferences, or any inventory data. Marking a build complete is your own record of what you built — Schemdeck does not verify or publish it. Profile pictures are stored in a private location that only your own signed-in session can access. You can remove any saved, in-progress, or completed build from your workbench at any time.
After you mark a build complete, the Manual’s final page may offer an optional “Yes — this worked” button. It is never required, and nothing is recorded unless you deliberately press it. If you do, Schemdeck stores one success report tied to your account for that Blueprint — the Blueprint’s identifier and when you reported it — and each account can report a given Blueprint only once; a report cannot be edited or undone from within the product. This is information you choose to provide, not passive browsing tracking, and it is separate from your private build history. The only thing shown publicly is the total number of success reports for each Blueprint, as a small check mark and count on its catalog card. Who reported, when, and any individual’s history are never shown: there is no public profile, contributor list, or activity feed. A success report is a user-reported claim — Schemdeck does not verify it, and it does not change a Blueprint’s validation status. Removing a build from your workbench does not withdraw a success report you already submitted, so it stays in that Blueprint’s total until you delete your account.
You can delete your account yourself from Account settings; the account, its sign-in records, its workbench profile, its inventory, its saved/in-progress/completed build records, its success reports (which lowers the affected Blueprints’ public totals accordingly), and any stored profile picture are removed, along with any locally stored billing state. If the account has a stored billing record that blocks self-service deletion, contact schemdeck@gmail.com to complete the request. Providers such as Supabase and Stripe may retain some records independently where they are required to.
Technical information
To operate and secure the site, the hosting and infrastructure providers Schemdeck uses may process standard technical request information, such as IP address, browser and device information, and request or diagnostic logs. This is normal server and network operation, separate from the workbench profile described above.
Cookies and tracking
Schemdeck uses Vercel Web Analytics and Vercel Speed Insights to understand aggregate site traffic and real-world page performance. Both record anonymous, aggregate data points only — such as the page visited, referrer, approximate geolocation, browser, and device type for Web Analytics, and page load/Web Vitals performance metrics for Speed Insights — without third-party cookies; Web Analytics identifies a visit only by a short-lived hash derived from the request, discarded after 24 hours, and per Vercel’s own privacy documentation neither tool collects information that identifies or re-identifies an individual, or that could reconstruct someone’s browsing activity across other sites or apps. Neither tool is used for advertising, shared with advertisers, or used to build a behavioral profile of any visitor, and neither feeds Schemdeck’s own recommendation or personalization system — as described above, that system uses only what a signed-in user deliberately provides. No custom analytics events are configured. Beyond this, Schemdeck does not set advertising or behavioral tracking cookies, and does not itself log, tied to your identity or account, which pages you visit, what you search for, or which catalog filters you use. Provider-level cookies or logs that are strictly necessary to serve and protect the site, and to keep you signed in, may still exist as part of normal hosting.
Payments
Schemdeck Pro is a recurring monthly subscription processed through Stripe. Stripe is the payment processor and handles payment-card details directly — Schemdeck never receives or stores your full card number. Schemdeck stores only the billing references and state needed to associate a Stripe customer and subscription with your account and to determine Pro access: a Stripe customer reference, a subscription reference, and the subscription status; see “Infrastructure providers” below. Stripe and other payment-related providers may retain their own records independently of Schemdeck, for as long as their own legal and operational obligations require.
Infrastructure providers
Schemdeck uses Supabase for authentication, for the billing state described above, for the private workbench data described in “Information you provide” (profile, preferences, inventory, saved and completed builds, and profile pictures), and for the optional success reports described there. Stripe is used for billing. Vercel hosts the site and provides the aggregate, anonymous Web Analytics and Speed Insights measurement described under “Cookies and tracking”. These providers process only the data needed to deliver those functions.
Sale of personal information
Schemdeck does not sell personal information.
Data retention and deletion
Support emails and operational logs are retained only as long as reasonably necessary for support, security, legal, and operational purposes. You can contact schemdeck@gmail.com with privacy questions or a reasonable request to delete information that Schemdeck actually controls. Schemdeck cannot promise deletion of data held independently by third-party providers beyond its control.
Changes to this policy
This policy may be updated as accounts, payments, analytics, or other features are introduced. The “Last updated” date above reflects the current version.
