Privacy

The short version

• Your organization decides what its check-in form asks. We store your answers and your check-ins so the organization can see who came.
• We don't sell your data, show ads, or use tracking cookies.
• Data is kept while your organization uses Checkerd and deleted within 30 days after it leaves.
• To see, fix or delete your data, ask your organization or email [email protected].

Who is responsible for what

When you register with an organization (a club, chapter or campus group), that organization decides which questions are asked and what the answers are used for. Checkerd processes that data on the organization's behalf, as its service provider. For the marketing site and pilot requests, Checkerd decides how data is used.

What we collect

• Registration answers. Your first and last name, phone number or email (whichever your organization uses for sign-in), and any other questions your organization adds, such as graduation year.
• Check-ins. Which tag you tapped, which event it was for, and when.
• A device token. A random code saved in your phone's browser so the next tap is one step. We store only a scrambled (hashed) version of it.
• Wallet cards, if you add one. Your name and when you joined, placed on an Apple Wallet or Google Wallet card.
• Officer accounts. Name, email, a hashed password and, if turned on, an encrypted two-factor sign-in secret.
• Pilot requests. What you send through the request form, plus a one-way hash of your IP address used only to block spam.
• Technical data. Your IP address and browser details pass through our hosting providers to deliver pages and stop abuse (for example, rate limiting). We don't use them to profile you.

Organizations should not use Checkerd to collect sensitive information such as Social Security numbers, financial account numbers, or health information.

How we use it

• To check you in, prevent double counting, and show your organization's officers attendance, member lists and streaks.
• To copy each check-in into your organization's own Google Form and Sheet, when the organization has set that up.
• To create Wallet member cards when you ask for one.
• To send officers sign-in, invite and password emails, and to reply to pilot requests.
• To keep the service secure, fix problems and prevent abuse.

Who can see it

• Your organization's officers, each through their own login. Member data is only reachable through our server, never directly from the browser.
• Your organization's Google Form and Sheet, if it uses one. Once there, the organization and Google's terms control it.
• Service providers that run Checkerd for us: Cloudflare (hosting and database), Vercel (website hosting), Resend (email), and Apple and Google (Wallet cards, only if you add one). They may only use data to provide their service to us.
• Legal reasons. If the law requires it, or to protect people's safety or our rights.

We don't sell or rent personal information, and we don't share it for advertising.

Cookies and local storage

The marketing site uses no advertising or analytics cookies. Officers get one sign-in cookie for the dashboard. The check-in page stores your device token in your phone's browser storage so it remembers you; clearing your browser data removes it, and you can sign in again with your phone number or email.

How long we keep it

Member and check-in data is kept while your organization uses Checkerd. When an organization cancels, we offer its owners an export and then delete its data within 30 days. Pilot requests are kept for as long as we need to follow up, and deleted on request. Copies already in an organization's Google Sheet are controlled by that organization.

Your choices

You can ask to see, correct or delete your data. Contact your organization's officers, or email [email protected] and tell us which organization you checked in with. We may need to confirm it's you, and we'll respond within 30 days. Deleting your data from Checkerd doesn't remove rows already copied into your organization's Google Sheet; ask the organization for that.

Security

Data is encrypted in transit. Device tokens and passwords are stored only as hashes, two-factor secrets are encrypted, lookups are rate limited, and officer accounts are invite-only. No system is perfectly secure; if a breach affects your data, we'll notify your organization and, where the law requires, you.

Children

Checkerd is not meant for children under 13, and we don't knowingly collect their information. Organizations whose members are under 18 are responsible for getting any permission the law or their institution requires.

Changes and contact

If we change this policy, we'll update the date above and, for significant changes, tell organizations by email. Questions: [email protected], MVella Studios, Florida.

1. The service

Checkerd provides NFC check-in pages for your members, an officer dashboard, optional mirroring of check-ins into your Google Form and Sheet, and optional Wallet member cards. Features labeled “Limited rollout” or “Coming soon” may change or not be available, and are provided as-is.

2. Accounts

Officer accounts are created by invitation. Keep passwords private, turn on two-factor sign-in where you can, and remove officers who leave. You're responsible for what happens under your officers' accounts.

3. Your members' data

Your organization owns the data your members give it. You decide what your registration form asks, and you're responsible for telling members how you use their information, having a valid reason to collect it, and following any rules your school or national organization sets. Don't collect sensitive information such as Social Security numbers, financial account numbers or health information. We handle your data as described in the Privacy Policy and don't use it for anything else.

4. Packages and billing

• Prices and what each package includes are listed on the Packages page or in your written quote.
• Each package has a one-time setup fee. Monthly billing starts when your tags go live.
• Subscriptions are month to month. You can cancel anytime; cancellation takes effect at the end of the month you've paid for.
• The setup fee isn't refundable once your tags have shipped. We don't refund partial months.
• We'll give at least 30 days' notice before changing your price. Prices don't include taxes, which you're responsible for.
• If a payment is more than 30 days late, we may pause check-in until it's paid.
• Pilots run on the terms we agree with you in writing.

5. Tags and readers

NFC tags, and any reader included with a Custom package, become your organization's property once paid for. We ship them configured and make sure they work with Checkerd on delivery. After that, loss, damage and replacement are your responsibility; we can supply replacements at cost. Any manufacturer warranty passes to you.

6. Acceptable use

Don't use Checkerd to break the law, collect data members haven't agreed to give, harass anyone, or send spam. Don't try to get around security or rate limits, access other organizations' data, overload the service, or copy or reverse engineer it.

7. Other services

Google Forms and Sheets, Apple Wallet and Google Wallet are run by their providers under their own terms. We're not responsible for their availability or for data once it's in your Google Sheet.

8. Availability and changes

We work to keep Checkerd running, but we don't guarantee it will be uninterrupted or error-free, and we may need to take it down for maintenance. We may improve or change features; if a change significantly reduces what your package includes, we'll tell you first and you can cancel.

9. Ending service

You can cancel anytime as described above. We may suspend or end service if you seriously or repeatedly break these terms, don't pay, or put others at risk. When service ends, we'll offer your owners an export and delete your data within 30 days.

10. Disclaimers and liability

Checkerd is provided “as is.” To the extent the law allows, we disclaim implied warranties, including fitness for a particular purpose. We aren't liable for indirect or consequential losses, such as lost data, lost revenue or attendance records you relied on. Our total liability for any claim is limited to what you paid us in the 12 months before it arose. You agree to cover claims against us that come from your data, your officers, or your use of Checkerd in breach of these terms.

11. Law and disputes

These terms are governed by the laws of the State of Florida. Any dispute will be handled in the state or federal courts located in Florida, and both of us agree to that jurisdiction. Before going to court, we'll both try to resolve it informally by email.

12. Changes and contact

We may update these terms. We'll change the date above and email owners at least 30 days before significant changes take effect. Questions: [email protected], MVella Studios, Florida.
