Go-Kart Hippo Privacy Policy

Last updated: October 20, 2026

YETZER Investment Group LLC (“we,” “us,” or “our”) operates the Go-Kart Hippo mobile application (“Go-Kart Hippo” or “the app”). This policy explains what information Go-Kart Hippo collects, how it’s used, who it’s shared with, and the choices you have over your data.

If anything in this policy is unclear, you can reach us at support@yetzerinvestmentgroup.com.

Who Go-Kart Hippo is for

Go-Kart Hippo is a scheduling and billing app for independent service professionals. The person using the app — the “provider” — runs their own business and uses Go-Kart Hippo to track clients, appointments, and payments.

A client appears in a provider’s data because the provider added them. Separately, clients can hold their own Go-Kart Hippo account, sign in, and see the visits, documents and balances their provider shares with them. A client’s account shows only what her own providers have shared. A client’s account also holds what she saves in it: the payment apps she adds (Venmo, Cash App, Zelle or PayPal), so a provider can ask to be paid there, which only that provider sees, and the names she gives her places.

A record that a provider removed one of your places: which provider, and when. Never the address.

What information we collect

Information you provide as a provider. When you sign up and use Go-Kart Hippo, you give us:

• Your email address (used to sign in)
• Your business name and your name
• Your timezone and working hours
• An optional profile photo
• Your payment handles (Venmo username, Cash App $cashtag, Zelle phone or email, PayPal handle) — used to generate payment-request links you send to your own clients

Information you create about your clients. As you use Go-Kart Hippo, you enter information about the people you serve:

• Their names, phone numbers, email addresses, and physical addresses
• Notes you write about them
• Appointments you schedule for them
• Invoices, estimates, and receipts you create for them

You are responsible for the information you collect about your clients. Go-Kart Hippo stores this information so you can run your business.

When you choose to send one, Go-Kart Hippo emails the recipient on your behalf — an invoice, an estimate, a receipt, or a note that a visit moved. The recipient doesn’t need to already be a client of yours. We do not message anyone for our own purposes.

Information from your device. When you use certain features:

• Location — Go-Kart Hippo uses your phone’s location to give you driving directions to a client’s address, and, when you tap Send ETA, to work out when you’ll arrive so you can text that time to your client from your own phone. For the arrival time, your position at that moment is sent through our server to Google, which calculates one driving route. We do not store your position or keep a log of it. When you take a card payment in person with Tap to Pay on iPhone, Stripe’s payment software on your phone reads your location during the payment, because Stripe needs to know where a payment happens to reduce fraud and disputes and turns in-person payments off when it can’t. That location goes to Stripe, not to us.
• Photos — Go-Kart Hippo asks for permission to access your photo library only when you tap to set a profile picture. The photo you select is uploaded to our storage so it appears on your account.
• Face ID / Touch ID — Go-Kart Hippo asks for biometric permission only if you turn on App lock, an optional switch in Settings → Account. With App lock on, Face ID or Touch ID (or your phone’s passcode) opens the app. The check happens on your device; we never receive or store your biometric data. The only thing we keep is whether App lock is on, saved with your account so it applies on each phone you sign in on.

Ask Vis. If you use Ask Vis, the assistant described under Ask Vis below, we keep a short record of that use. Your questions and Vis’s answers are not among it.

Information collected automatically. Go-Kart Hippo uses Sentry (sentry.io), a third-party crash-reporting service, to receive notifications when the app crashes or errors. Sentry receives technical information about the crash (device type, operating system version, the line of code that failed). We have configured Sentry to scrub IP addresses and to not associate crashes with your account email.

How we use this information

We use the information to:

• Provide the scheduling, billing, and document-generation features that are the purpose of the app
• Sync your data across your devices when you sign in
• Diagnose crashes and bugs through Sentry
• Send you transactional messages tied to your account (such as deletion confirmations)
• Answer your questions in Ask Vis, if you turn it on, and keep its daily and monthly limits

We do not use your information for advertising. We do not profile you, build behavioral models, or sell your information to anyone, ever.

Who we share information with

Go-Kart Hippo does not sell, rent, or trade your information.

We share information only with the following service providers, and only to the extent necessary to operate the app:

• Supabase (supabase.com) hosts our database and storage. Your provider account data and the client data you enter is stored there.
• Sentry (sentry.io) receives crash reports as described above.
• Apple (apple.com) bills and manages paid subscriptions bought on an iPhone, through the App Store. Apple receives your purchase and subscription status. If you subscribed on the website, Apple is not involved and receives nothing.
• RevenueCat (revenuecat.com) manages subscription state for subscriptions bought on an iPhone, and receives purchase events. It is not involved in a website subscription. Your device contacts RevenueCat whenever you are signed in on a phone — not only when you buy — and sends an app-user identifier tied to your account. That identifier is a token created for this purpose and is not your account’s own identifier.
• Cloudflare (cloudflare.com) hosts the web app and the client-facing booking pages, and therefore handles connection data such as IP addresses for anyone who opens a booking link.
• Twilio (twilio.com) holds a phone number for a future feature. The app does not use it today, and no message has been sent through it.
• Google (google.com) provides address autocomplete. When you type a client’s street address, what you type is sent to Google Places to suggest and confirm it. This means a client’s street address — typed by you, about a person who has not agreed to anything with Google — is sent to Google. Google also works out the arrival time when you tap Send ETA: your position at that moment and your client’s address are sent to Google to calculate one driving route. We keep only Google’s identifier for the address (a place ID), not your position or the route.
• Resend (resend.com) delivers the emails you send to your clients.
• Anthropic (anthropic.com) writes Vis’s answers when you use Ask Vis. What it receives is described under Ask Vis below.
• ElevenLabs (elevenlabs.io) turns Vis’s answers into speech when you turn on Vis’s voice. What it receives is described under Ask Vis below.
• Stripe (stripe.com) processes subscription payments and gift purchases. If you set up a payout account so clients can pay you through Go-Kart Hippo, you enter your identity and bank details into Stripe’s own form; those details go to Stripe and not to us, and we store only your bank’s name and the last four digits of the account. When the client-payment feature is switched on, a client paying one of your bills will enter their card details directly with Stripe — we will never see or hold them. That feature is built but not yet reachable by clients; no client has paid through it.

When you tap a payment-request button in Go-Kart Hippo to send a Venmo, Cash App, Zelle, or PayPal payment link to your client, the relevant payment app opens with the request pre-filled. Go-Kart Hippo does not process the payment, does not see the payment confirmation, and does not share information with these payment services beyond what’s contained in the link you send.

We may disclose information if required by law (a valid subpoena, court order, or equivalent), or to protect our legal rights. If this happens and we are not legally prohibited from telling you, we will.

Ask Vis

Ask Vis is an optional assistant for providers on the Premium plan. It answers questions about your own visits, clients and money. It can also suggest a change — booking a visit, adding a client, marking a visit paid, moving or cancelling a visit, adding a note, or changing a price — and the change happens only if you confirm it.

Nothing is sent until you agree. The first time you open Ask Vis, it shows what is sent and asks for your consent. You can withdraw your consent at any time in Settings → Vis, and nothing more is sent after that. If what is sent, who receives it, or how long they keep it changes, Ask Vis asks you again.

What is sent, and to whom. When you ask a question, our server sends it to Anthropic, which runs the Claude models that write Vis’s answers. Along with your question it sends:

• your earlier questions and Vis’s answers from the conversation that is open now — nothing from earlier conversations;
• today’s date and your time zone;
• only the records needed to answer, such as client names, visit dates and times, prices, whether a visit is paid, monthly totals, and the open times in your schedule.

Notes you wrote about a client are sent only when you ask about notes, or ask what you should know about a client, and gate, alarm and lockbox codes in them are hidden unless you ask for a code. Vis doesn’t read your clients’ phone numbers, email addresses or street addresses from your records. If you give Vis a phone number or an address — to add a client or book a visit — it is sent with your question, so Vis can fill in the card you confirm.

What Anthropic does with it. Anthropic does not use it to train its models. Under Anthropic’s standard terms it may keep it for up to 30 days and then deletes it. We have asked Anthropic not to keep it at all; if that is granted, we will update this policy and ask for your consent again.

Asking by voice. On iPhone you can speak a question instead of typing it. Your iPhone turns your speech into text on the device. No audio is sent to us or to Anthropic — only the text, when you send the question.

Vis’s voice. In the web app, Vis’s answers can be read aloud. The voice is off until you turn it on with the speaker button in the conversation, and that choice is kept on the device you made it on. When it is on, our server sends the text of each answer to ElevenLabs, which turns it into speech. Only the answer’s text is sent — not your question and not your records — though an answer can name a client, a date or an amount. Before the text is sent, our server removes street numbers, apartment numbers and postcodes, phone numbers, email addresses, web links, payment handles such as @names and $cashtags, and long numbers such as card or account numbers, so Vis never reads out a full address, a phone number or payment details. Nothing is sent to ElevenLabs while the voice is off. The consent sheet names ElevenLabs; if you agreed to Ask Vis before the voice was added, Ask Vis asked you again.

What ElevenLabs does with it. ElevenLabs does not use it to train its models: our account’s training setting is switched off. ElevenLabs keeps a copy of each spoken answer in our account until it is deleted, and we delete each one right after Vis has spoken it. If a deletion does not go through at once, our server tries again every few minutes, and Vis stops reading answers aloud for everyone if a copy is still held after 15 minutes.

What we keep. We do not store your questions or Vis’s answers. The conversation stays on your phone and is cleared when you close it. We keep:

• each time you give or withdraw consent, with the terms in force at that moment;
• for each question, the day you asked it, whether it was answered, how many steps it took and what it cost, so we can keep the daily and monthly limits;
• your Helpful or Not helpful rating, if you give one;
• for each answer read aloud, how many characters were sent, what it cost, and whether its copy at ElevenLabs was deleted;
• for each change you confirm, what it changed and what it was before, so you can undo it from Activity for 24 hours.

These records are kept while your account is active and are deleted with it.

Text messages to your clients

Go-Kart Hippo does not text your clients. When you send an On my way message, an arrival time or an evening reminder, your phone’s own Messages app opens with the text written, and you send it from your own number. It does not go through us.

How we store and protect information

Your data is stored on servers managed by Supabase, hosted in the United States. Communication between your device and Supabase is encrypted in transit (HTTPS / TLS). Database access is gated by row-level security so providers can only read and write their own data.

No system is ever 100% secure. If we discover a breach affecting your data, we will notify you by email and, where required by law, by the means specified by that law.

How long we keep your data

We keep your account data for as long as your account is active.

If you delete your account, your data enters a 7-day cool-down period during which you can cancel the deletion. After 7 days:

• A provider account: all of your provider account data, client records, appointments, invoices, notes and Ask Vis records are permanently deleted from our database, and your uploaded photos are permanently deleted from our file storage as well as from the database.
• A client account: your sign-in, your email address, your connections to your providers, the updates they have shared with you, and everything you saved in your account (your payment apps and the names you gave your places) are permanently deleted from our database. Your providers keep their own records of the work they did for you; those records are theirs and are covered by the provider sections of this policy.

Backups containing your data are rotated within the timeframe specified by our hosting provider’s policies.

Children’s privacy

Go-Kart Hippo is not designed for, marketed to, or intended for use by children under 13. We do not knowingly collect personal information from children under 13.

Your rights if you live in California

If you are a California resident, the California Consumer Privacy Act (CCPA) gives you the right to:

• Know what personal information we have collected about you
• Delete the personal information we have collected about you
• Correct inaccurate personal information we hold about you
• Opt out of the “sale” or “sharing” of your personal information — Go-Kart Hippo does not sell or share your personal information, so this right is automatic

To exercise these rights, email support@yetzerinvestmentgroup.com. We will respond within 45 days. We will not discriminate against you for exercising any of these rights.

Your rights if you live in the European Union, United Kingdom, or European Economic Area

If you are in the EU, UK, or EEA, the General Data Protection Regulation (GDPR) gives you the right to:

• Rectify inaccurate or incomplete personal data
• Erase your personal data (“right to be forgotten”)
• Restrict how we process your data
• Receive your data in a portable format
• Object to certain types of processing
• Lodge a complaint with your local data protection authority

The legal bases on which we process your data are: your consent (for optional features like Sentry crash reporting and Ask Vis), the performance of a contract (operating the app you signed up for), and our legitimate interests (security, fraud prevention).

To exercise any of these rights, email support@yetzerinvestmentgroup.com. We will respond within 30 days.

Changes to this policy

If we change this policy in a way that meaningfully affects how we handle your information, we will update the “Last updated” date at the top and, where the change is material, notify active providers by email or by an in-app banner before the change takes effect.

Governing law

This policy is governed by the laws of the State of Florida, United States, without regard to conflict-of-law principles. Any dispute arising from your use of Go-Kart Hippo or this policy will be resolved in the state or federal courts located in Florida.
