Privacy Policy

Effective date: October 26, 2026

This policy explains what information Best Up collects, why we collect it, and the choices you have. Best Up is run by Kai Ishii, a sole proprietor in Florida, USA. "We" and "us" mean Kai Ishii.

1. What this policy covers

• Our website.
• The Best Up web app.
• Our iPhone and iPad app on the Apple App Store.
• Our Android app on Google Play.

Best Up is built for businesses. Most of the information in it belongs to the dealership that uses Best Up, which is usually your employer. If you have questions about how your dealership uses Best Up, ask your manager or admin.

2. What we collect

• Staff accounts. Names, email addresses, phone numbers, profile photos, and job roles of dealership staff.
• Customer names. Names of dealership customers that staff enter into Best Up.
• Dealership setup. The dealership's name, store and rotation settings, team roster, and roles.
• Queue and activity records. Up-list positions, statuses such as available or on break, rotation events, visit outcomes such as test drive or sold, and when each happened.
• Messages. Messages staff send each other in Best Up.
• Usage and device details. IP address, device and browser type, operating system, app version, and how the service is used. We use this for security, fixing problems, and making Best Up better.
• Location checks. If your dealership turns on a showroom boundary, we check your device's location when you take a protected queue action. This only happens while you use the app. We do not track your location in the background, and we do not save the exact coordinates in your dealership's records.
• Demo and contact requests. The details you send us, such as your name, work email, dealership name, phone number, and message.
• Website assistant chats. The questions you ask the Ask Best Up assistant on our website, its answers, and the page you asked from. We do not save your name or IP address with them. To limit abuse, we keep a one-way code made from your IP address for about an hour to count how many questions you ask.

3. Sign-in, payments, and analytics

• Sign-in. Clerk handles sign-in and user accounts.
• Payments. Stripe processes subscription payments. The payment details you give Stripe are handled by Stripe.
• Usage analytics. PostHog tells us how people use our marketing pages. The next section explains how.

4. Cookies and analytics

We use essential cookies to run and secure Best Up. These cover sign-in, sessions, security, your theme, and your cookie choice. You cannot turn them off, because Best Up needs them to work.

PostHog only runs on our public marketing pages. It does not run on sign-in, sign-up, onboarding, the dealership web app, or our mobile apps. It shows us which pages people visit, how far they scroll, what they click (such as Book a demo), how fast pages load, and whether a demo request went through. We never send the names, emails, phone numbers, or messages you type into our forms to PostHog.

If you accept optional cookies, PostHog saves an ID in your browser for your current visit, so it can link the pages you view. It also records your visit so we can replay how the site was used, including clicks and scrolling. Anything you type into a form is hidden in these recordings. We do not record console logs or network request contents. Recording only happens after you accept.

If you choose No thanks, or ignore the cookie banner, we still count visits and clicks, but without cookies. PostHog saves nothing in your browser and does not record your visit. To avoid counting a visit twice, PostHog mixes details your browser already sends (such as IP address and browser type) with a secret value that changes every day. It turns that into a one-way code. The code cannot be traced back to you, and it cannot link your visits across days.

Either way, we note which website sent you to us and any campaign tags in the link, such as utm_source or utm_campaign. This shows us which ads, emails, and partners bring people to Best Up. We do not use advertising or cross-site tracking cookies. You can change your choice at any time with Cookie preferences in the website footer.

5. How we use information

• To run, maintain, and secure Best Up.
• To run the up-list rotation, build your dealership's reports, and send notifications and messages.
• To apply showroom boundaries your dealership sets up.
• To answer questions, give support, and schedule demos, and to improve the website assistant's answers.
• To bill for subscriptions.
• To check performance, fix problems, and improve Best Up.
• To follow the law and enforce our terms.

6. Who we share information with

We do not sell your data. We share information only in these cases:

• Within your dealership. Managers and teammates can see queue positions, statuses, visit outcomes, activity logs, and messages, based on the roles your dealership sets.
• Service providers. Clerk (sign-in), Stripe (payments), Convex (database), Vercel and Expo (hosting and app delivery), PostHog (marketing site analytics), and Anthropic, whose Claude model writes the website assistant's answers from the questions you send it. They use data only to provide their services to us.
• When the law requires it. We may share information to comply with a law, subpoena, or court order, or to protect our rights, our users, or the public.
• If the business changes hands. If Best Up is sold or merged, information may move to the new owner, still under this policy.

7. How long we keep information

We keep information while your dealership's account is active, or as long as we need it to run Best Up, settle disputes, and follow the law. We keep queue and activity records so your dealership can see past reports. When a dealership ends its subscription, we delete its data or remove what identifies people within a reasonable time, unless the law requires us to keep it. We delete website assistant chats after 12 months.

8. Deleting your data

You can ask us to delete your account and personal data. In the mobile app, open Profile and choose Delete account. You can also email team@bestuplist.com from the email address on your account. Our account deletion page has the steps. Your dealership may keep business records it controls, such as past queue activity and reports, where it needs them for business or legal reasons.

9. Your rights

You can update your account details in your profile settings. Depending on where you live, you may have the right to see, correct, delete, or export your personal information. Because most data belongs to your dealership, we may send some requests to your dealership's admin.

10. Security

We protect information with standard safeguards, including encryption in transit, access controls, and role-based permissions. No system is completely secure, so we cannot promise perfect security.

11. Children

Best Up is for dealership staff. It is not meant for children under 16, and we do not knowingly collect information from them.

12. Changes to this policy

We may update this policy. For important changes, we will tell you in Best Up or by email before they take effect. The effective date at the top shows when we last changed it.
