Split3MF values user privacy and treats privacy as part of the product. The data controller for Split3MF is Taejoo Um, operating as Morpii. Address: Unit 201, 2F, 9 Daecheongbuk-gil 17beon-gil, Jung-gu, Busan, Republic of Korea. For privacy requests, contact [email protected] or call +82 502-6681-7382.
Split3MF processes the 3MF, OBJ & STL files you load to provide the features you use, such as viewing, splitting, cutting, editing and exporting models.
If you sign in, Split3MF stores your email address and sign-in data with Supabase. Passwords are stored only in hashed form. If you sign in with Google, Google shares your email address, name and profile picture with Split3MF. To allow one active sign-in per account, we store the current session ID and sign-in time. We also store daily upload and download counts for your account, with the country and time zone used to determine the day. Split3MF does not store your model file names, model labels, or model contents for these counts.
Paddle processes Pro subscription and one-time payments. We store your account ID, Paddle customer, subscription and transaction IDs, subscription status and paid periods in Supabase to manage Pro access. We do not store card details.
Split3MF sends account emails, such as sign-up confirmation and password reset, and emails about your Pro purchase. We may also send emails about Split3MF updates, and each one includes an unsubscribe link. If you unsubscribe, we keep your email address, language and the date so that we do not email you again. Emails are sent through Resend.
To reduce automated abuse, Split3MF uses Cloudflare Turnstile on account forms such as sign-up and sign-in, together with email verification, rate limits and usage limits. Turnstile checks signals such as your IP address and browser and device characteristics.
Outside China, Split3MF uses Google Analytics and PostHog to understand basic product usage, such as page visits and feature interactions. Google Analytics may process sanitized page URLs, browser and device information, IP-derived location, and cookie or consent signals. It is not loaded on authentication callback pages, advertising and personalization signals are disabled, and analytics storage defaults to denied in regions requiring consent. PostHog session replay is disabled. Analytics are used to improve the tool and are not used to inspect your model file contents.
To show how many people are using Split3MF right now, each open page sends a random ID created for that tab, and we record it with your country. Each record is deleted about 10 minutes after the tab stops sending it.
Split3MF displays a Google AdSense banner to help fund the service. Google and its advertising partners may use cookies, IP addresses, browser information, and ad interactions to deliver and measure ads, subject to applicable consent choices. Advertising code is not loaded on authentication callback pages or in China mode. Model file contents are not sent to Google by this integration.
Split3MF uses your browser's storage for your language and settings, your sign-in session and the work you save to reopen. Google Analytics, PostHog and Google advertising use their own cookies or identifiers, as described above. You can delete or block cookies and site data in your browser settings; doing so signs you out and removes saved settings and work. You can turn off personalized Google ads at myadcenter.google.com.
Split3MF is operated from the Republic of Korea and uses the following providers, so your information is processed in the countries listed.
| Provider | Purpose | Location |
|---|---|---|
| Cloudflare | Hosting and delivering the site, security and bot protection | United States and Cloudflare's global network |
| Supabase | Accounts and database | United States (Northern Virginia) |
| Analytics, advertising and Google sign-in | United States | |
| PostHog | Product analytics | United States |
| Paddle | Selling Pro as reseller, payments and refunds | United Kingdom and other countries where Paddle operates |
| Resend | Sending emails | United States |
Account-related data is retained while your account exists and is deleted when your account is deleted, unless a longer retention period is required by law or needed to resolve abuse, security, or support issues.
After account deletion, Split3MF keeps a hashed version of the deleted account email for 48 hours to prevent immediate re-registration with the same email. This temporary block is used only for the re-registration limit.
Pro billing records that Split3MF stores are deleted with your account, while Paddle keeps its own purchase records as the seller, as required by law. Support emails are kept as long as needed to handle your request and any related dispute. Unsubscribe records are kept until you ask us to delete them. Analytics and advertising data are kept according to the retention settings of Google and PostHog.
You can reset your password and delete your account in Split3MF, and unsubscribe from update emails with the link in each email. To access, correct or delete your information, or to object to or restrict how it is used, email [email protected]. We may need to confirm your identity first. Additional rights that apply in your country or region are listed below.
We protect your information with encrypted connections (HTTPS), hashed passwords, database access controls and administrative access limited to the operator. Payment card details are handled by Paddle and are not stored by Split3MF.
Split3MF is not directed at children. If you are under 14, or under the age at which the law of your country allows you to consent to the processing of your personal information, use Split3MF only with the consent of a parent or guardian. If we learn that we have collected a child's information without the required consent, we will delete it.
If you contact us by email, we may receive your email address and the information you choose to send. Do not send confidential model files unless you are comfortable sharing them.
You keep ownership of the model files and intellectual property you load into Split3MF. Split3MF does not claim ownership of your uploaded, processed, or exported model files.
When we change this policy, we update the date at the top. We announce important changes on the site or by email at least 7 days before they take effect, or at least 30 days before if they significantly affect your rights.
Information that Korean law requires us to keep is stored separately for the required period: records of consumer complaints and dispute handling for 3 years (Act on the Consumer Protection in Electronic Commerce). Records of Pro contracts, payments and refunds are kept by Paddle, the seller, as required by law.
We do not provide your personal information to third parties except with your consent or where the law requires it. When you buy Pro, you enter your payment information directly with Paddle, the seller, and we pass a checkout reference to Paddle so that the purchase is linked to your account.
Your personal information is transferred abroad as follows. It is sent over encrypted network connections when you use the related feature.
If you do not want these transfers, do not create an account, or delete your account or ask us at [email protected]. You can block analytics and advertising cookies in your browser or in Google's ad settings. Transfers to Cloudflare and Supabase are needed to provide the site and accounts, so if you refuse them you cannot use account features such as downloads and Pro.
When the retention period ends or the purpose has been achieved, we destroy the information without delay. Electronic files are deleted so that they cannot be restored, and paper records are shredded or incinerated.
You can ask to access, correct or delete your personal information, ask us to suspend its processing, or withdraw your consent, by email or phone. Your legal representative or a person you authorize can also make these requests for you. We respond within 10 days.
Google AdSense may collect behavioural information, such as visits and ad interactions, through cookies to show and measure ads. You can turn off personalized ads at myadcenter.google.com and block cookies in your browser.
