Privacy Policy

We collect only what we need to record your money and run the service:

• Who you are: your phone number, your chat platform and user ID, and the display name from that chat account.
• What you send: the text of the messages you send to record money, and any receipt images you attach.
• Your records: the transactions we create from your messages, including amount, currency, category, and date.
• Technical data: basic logs and timestamps needed to run the service securely and diagnose problems.

We use your information only to run Carterdia for you, never to sell your data or to serve advertising:

• To turn your messages into transactions and show your reports.
• To sign you in with a one-time code and keep your account secure.
• To convert between currencies for display in your reports.
• To fix problems, prevent abuse, and keep the service reliable.

To work out what a message means, we send its text, and any receipt image, to an automated model provider that returns the structured details we save. Receipt images are deleted right after they are processed, whether or not the reading succeeds. We keep the resulting transaction, not the image.

We share data only with the providers who make the service work, and only as far as they need it:

• Chat platforms (Telegram, and WhatsApp through Meta) to send and receive your messages.
• Model providers to read your messages and receipts and return structured data.
• Hosting and infrastructure providers that run our servers and the web dashboard.
• A currency-rate provider for daily exchange rates, which receives no personal data.
• If the law requires it, we may also disclose data to protect our users and the service.

You reach Carterdia through chat apps we do not control. The messages you send pass through Telegram or WhatsApp under their own privacy policies, and we receive them to provide the service. Please review those apps' policies to understand how they handle your messages on their side.

We keep your account and transactions for as long as your account is active, so your history stays available to you. Receipt images are deleted immediately after processing. When you delete your data or close your account, we remove your personal data within a reasonable period, except where we must keep something to meet a legal obligation.

Traffic to Carterdia is encrypted in transit. Access to the systems that hold your data is restricted, and we never store one-time codes or sign-in tokens in a readable form. No service can promise perfect security, but we take reasonable steps to protect your information.

You can see all of your transactions on the dashboard, and edit or delete any of them at any time. Depending on where you live, you may also have the right to request a copy of your data, correct it, or ask us to erase it. To make a request, contact us using the details below.

You can ask us to delete your account and all of its data at any time by writing to us from, or naming, the phone number on your account:

privacidad@carterdia.com

Our providers may process data in countries other than your own. Where that happens, we rely on providers that offer appropriate safeguards for international transfers.

Carterdia is not intended for anyone under 18, and we do not knowingly collect data from children. If you believe a child has used the service, contact us and we will remove the data.

We may update this policy as Carterdia changes. When we make a meaningful change, we will update the effective date at the top of this page.
