Terms of service

1. Purpose and scope

ChartDoum’s own engine and AI analyze chart photos uploaded by users and explain price action, key levels, and conditional interpretations. These terms set out the rights and obligations of the operator and users when using ChartDoum.

ChartDoum’s own engine and AI generate results automatically; no person writes, edits, or reviews individual results. They are technical interpretations of information visible in a photo, with no guarantee of profits or accurate price predictions. The service does not place orders or manage your assets.

2. Registration and accounts

Registration and sign-in are provided only through the social providers currently shown on the sign-in page; direct email and password registration is not provided. You must use an account you are authorized to use and must not impersonate others or access their accounts without permission.

3. Photos and analysis results

You must have the right to upload your photos. Remove information not needed for analysis, such as account numbers, order histories, and other people’s personal data, before uploading.

Image resolution, tilt, obstructions, the time of capture, and chart type can cause reading errors or missing information. Displayed prices refer to the time of the photo and may differ from live market prices.

If number notation is ambiguous, the input may include your price confirmation as well as the photo. This is your input, not a review by an operator, and may be incorrect. Parsed observations and the confirmation request are held in server memory for up to 10 minutes to continue the analysis; photos are not kept for this step. They are deleted after use or expiry. Waiting for confirmation does not use an analysis credit.

You decide whether to invest or trade. This information does not exclude the operator’s liabilities or your rights under applicable law.

4. Prices, subscriptions, and usage limits

The website provides app installation guidance. Available products, local prices, renewal terms, and applicable tax are shown in Google Play or the App Store before you confirm a purchase.

Each paid product shows its service period, total amount, taxes, included analyses and usage rules, extra-pack terms, automatic-renewal status, and next billing terms before payment. You can review these details before deciding to purchase.

Only a completed checkout confirmation creates a charge and grants analyses. The service applies the product, credit allowance, and usage rules shown at checkout and on the account page.

5. Cancellation, withdrawal, and refunds

If automatically renewing subscriptions are offered, the method and timing for stopping the next charge will be explained before purchase. Turning off renewal and refunding an existing payment are separate procedures. Remaining access and refunds will be handled according to the purchase terms and applicable law.

Refund eligibility and processing follow the refund policy and procedure of the app store used for the purchase (Google Play or the App Store). ChartDoum does not charge any separate refund fee or penalty, and this does not limit statutory rights.

Where the law requires express consent before immediate digital service begins, checkout will ask for that consent and acknowledgement of any resulting loss of a withdrawal right before an analysis can be used.

Request cancellation or a refund through the payment provider used for the purchase or the account page; the provider's process and this policy apply. Questions about use or payments can be sent to support@chartdoum.com.

6. Photo processing and usage records

Uploaded photos are processed transiently and are not retained on ChartDoum servers. A completed report may be kept on the server for up to 10 minutes solely to redeliver it if the network response is lost, and is then deleted. Photos and inputs are sent to an external AI provider for analysis.

Completed results and reduced-size photos are saved automatically in your browser. Only the 10 most recent are kept, and older records are removed automatically. They may be lost if you clear browser data or change devices and do not sync to another device or your account.

The Privacy Policy explains the data, purposes, retention periods, and user choices for account, payment, security, and optional features.

7. Use restrictions and service changes

We may restrict illegal uploads, infringement of others’ rights, account misuse, attacks on the system, or excessive load from unauthorized automation. We will explain the reason and how to appeal; urgent security action may be taken before notice.

Maintenance, outages, or problems with an external AI provider may delay or interrupt the service. Significant planned changes will be announced in advance. Interruptions or closure affecting paid access will be handled under applicable law and the contract terms.

8. Changes to these terms and contact

When these terms change, we will make the changes, reasons, and effective date available to users. Separate consent will be obtained where required, and changes will not be applied retroactively to users’ disadvantage contrary to law.
