AppFerry ("we", "us") converts Bubble apps into code that you can run anywhere. This policy covers getappferry.com and the AppFerry service. We collect only what we need to run the service, we don't sell personal data, and we don't use it for advertising.
What we collect
- Your account. Your name, email address and password. We store the password only as a secure hash.
- Your apps. The Bubble apps you ask us to convert: their name and version, their design and logic as Bubble provides it, and what we make from them (the code, the preview and logs). We remove secrets such as API keys from your app's settings before we convert it.
- Your app's data, only if you ask for it. If you choose to copy your data, you give us a Bubble Data API token and we read your app's records with it. We use the token for that copy only and delete it as soon as the copy ends. The copied records stay with your conversion until you delete them.
- AI connections, only if you set one up. If you connect your own Claude or ChatGPT account to fine-tune your app, we keep the sign-in it gives us so we can work on your app for you. Disconnect it from your account page at any time and we delete it.
- Payments. Polar sells our subscriptions as the merchant of record: it takes your payment, your billing details and any tax ID, under its own privacy policy. We never see your card number; we keep which of your apps are subscribed and until when.
- Technical data. Like any website, our servers and our hosting provider see your IP address, browser and the pages you request, and keep them in short-lived logs to run and protect the service.
- Usage statistics. We use Plausible to count visits: which pages are viewed, where visitors come from, their country and device, how long they stay and which main buttons they press. It uses no cookies, doesn't keep your IP address and doesn't identify you or follow you to other websites.
- Launch updates. If you leave your email to hear when we launch, we keep it only for that and send you one message. Ask us to remove it at any time.
- Messages. If you email us, we keep the conversation so we can help you.
Cookies
We use one cookie: it keeps you logged in, it's needed for the service to work, and it expires after you log out or after a while. We don't use analytics, advertising or tracking cookies: our visit statistics need none.
How we use it
- To convert your apps, show you previews and let you download them.
- To run your account and billing, and to email you about them.
- To keep the service secure, fix problems and prevent abuse.
- To meet our legal obligations, for example keeping payment records.
We don't use your apps or your app's data to train AI models, and we don't look at them except when you ask us for help or when we must to keep the service running or secure.
AI fine-tuning
Fine-tuning is optional. When you start it, an AI assistant works on the converted code of your app in an isolated environment that can reach only the files of that conversion. It uses the account you connected, so your app's code is sent to that provider (Anthropic for Claude, OpenAI for ChatGPT) under your agreement with them. We write the instructions; nobody else can talk to the assistant.
Who we share it with
Only with the services that help us run AppFerry, and only what each one needs:
- Polar (and its payment processor, Stripe) for payments.
- Cloudflare and our hosting provider, which host the website and the service.
- Plausible for cookie-free visit statistics, as described above.
- Proton for our email.
- Bubble, which we read your app from.
- Anthropic or OpenAI, only if you fine-tune with your own account, as described above.
We may also share data when the law requires it, or with a company that takes over AppFerry, which would then have to protect it as this policy does. Some of these services are in the United States or other countries; where the law requires, we use safeguards such as standard contractual clauses for those transfers.
How long we keep it
- Conversions, with their code, preview and copied data, until you delete them.
- Copied data on its own, until you delete it from the conversion or delete the conversion.
- Data API tokens, only while a copy runs.
- Your account, until you ask us to delete it. We then delete it and everything in it within 30 days, apart from payment records we must keep by law.
- Launch sign-ups, until we've sent the launch email, or until you ask us to remove them.
- Server logs, for a few weeks.
How we protect it
Connections to AppFerry are encrypted, passwords are hashed, tokens are deleted when they're no longer needed, and each conversion and each AI session runs separately from the others. No system is perfectly secure, but if a breach affects your data we'll tell you without undue delay.
Your rights
You can see, correct, download or delete your data. Most of it you can manage yourself: change your password and AI connections on your account page, and delete conversions or copied data at any time. For anything else, including a copy of your data or deleting your account, write to support@getappferry.com. We answer within 30 days. Depending on where you live, you may also be able to object to how we use your data, restrict it, or complain to your data protection authority.
Your app's users
When you copy your app's data, you're the one deciding what happens to your users' information, and we process it for you, only to provide the service. Make sure you're allowed to copy it, and tell your users about it where the law requires.
Children
AppFerry is for businesses and builders, not for children under 16, and we don't knowingly collect their data.
Changes
If we change this policy, we'll update it here and change the date above. If the change is significant, we'll also tell you by email before it takes effect.
