Privacy Policy

1. What we collect

When you use Stringle, we store the account details, business settings, quotes, invoices, customers and cost items you enter. We do not access your bank, payment processor or accounting software.

2. How we use it

Your data is used to run the app — building quotes and invoices, tracking payments and showing your dashboard. On Base44’s current plans it may also be used by Base44 to train AI models, as set out in the next section. We never share your private costs, margins or break-even figures with your customers.

3. AI model training

Stringle runs on the Base44 platform. On Base44’s current plans, data stored in the app — including the customer names, addresses and job details you enter — may be used by Base44 to train AI models. Base44 provides no opt-out for this below its Enterprise tier, which Stringle is not on. If that is not acceptable for your customer records, you can use a job reference instead of a customer name.

4. Where it lives

Your data — account details, business settings, quotes, invoices, customers and cost items — is stored on servers operated by Base44 (the platform Stringle is built on). Base44’s servers are currently located in the United States. Data is encrypted at rest and transmitted over an encrypted connection.

Because Base44 operates the database and infrastructure that run Stringle, Base44’s staff can access stored data in order to operate and maintain the service. Your costs, margins and break-even figures are never shown to your customers — that separation is enforced in Stringle’s code — but they are not hidden from the platform that hosts them.

Outside of hosting and operating the service, the third parties that may receive your data are the email provider used to send messages from the app and, when payments are enabled, Stripe (your subscription billing). See “Your data” below for export, retention and deletion.

Security and compliance controls are operated by Base44 as the hosting platform, not by Stringle. Base44 is compliant with SOC 2 Type II and is ISO 27001 certified. Emails sent by Stringle come from the base44-apps.com domain. To request a copy of the personal data Base44 holds about you, email compliance@base44.com from the email associated with your account.

5. Customer documents

Quotes and invoices you send to your customers are generated as PDFs and shared directly by you. Stringle does not email your customers on your behalf and does not retain their contact details separately from the records you create.

6. Your data

You can export a full backup of your account at any time, from the Backup button inside the app. A backup includes your business settings, your cost items (the catalogue), every quote, every invoice, and every customer. It is a plain JSON file you can keep, move to another account, or hand to an accountant.

We do not delete your data automatically. There is no scheduled purge, no expiry on a lapsed subscription, and no “trash” that empties itself. Your records stay exactly where they are until you remove them.

Deletion is something you do, not something that happens to you. You can clear your workspace data from inside the app, or email hello@stringle.app to ask us to remove your account. We action a deletion request when we receive it; we do not retain a copy beyond what the hosting platform (Base44) keeps to operate the service, which we cannot remove on your behalf.

Stopping your subscription does not delete your data. If your subscription lapses or you cancel, you keep read access to everything you entered, and you can export it at any time. Cancellation terms are in the Refunds & Cancellations policy.
