01What the app stores on your device

MadeMargin stores your materials, product recipes and photos, costing inputs, pricing history, selling-channel fee settings, and recorded sales in app-owned storage on your device. It also stores preferences such as language, currency, measurement units, appearance, craft categories, and haptics, together with a temporary calculator draft.

This information lets you calculate material, labor, packaging, and other costs; set selling prices; compare channels; plan batches; save products; and review the sales you record. Preferences keep the app working the way you choose.

There is no account or automatic cloud sync. Pricing works offline, and business records are not automatically uploaded to a MadeMargin server. The app currently has no advertising or usage-tracking analytics. The sales summaries you see in the app are calculated from your local records.

02Optional support requests

Contact Support is optional and needs an internet connection. It lets you ask for help, report a problem, or send feedback or a suggestion. When you choose Send request, the app sends the following to the support service over HTTPS:

• Your email address, optional name, selected category, subject, and message.
• One image, if you choose to attach it. Supported image types are JPEG, PNG, and WebP.
• The app identifier and version, operating system and version, device model when available, and current formatting locale.
• A random, persistent installation identifier (UUID) generated by the app. This is not an advertising identifier, device serial number, or IMEI.

03How support information is used

Your message and chosen image help explain your request, and your email address allows a reply. App and device details provide context for investigating a reported problem. The installation UUID identifies the app installation for support submissions; a successful request is given a reference so it can be followed up.

The shared support service uses submitted information to respond to requests, troubleshoot issues, prevent abuse, and maintain necessary support records. Infrastructure and service providers may process it to operate, host, deliver, secure, or maintain that service. Support messages, names, email addresses, and images are not used for advertising.

Business records are not automatically attached to a support request. Anything you type into the message or put in a chosen image is sent, so avoid including private business information or other sensitive details that are not needed.

04Secure support identifiers

The app keeps the installation UUID and the latest successful support reference in operating-system secure storage. These values are separate from business records and preferences and are not included in MadeMargin’s manual business backups.

The support form does not keep a local history of submitted messages or contact details. Unsent form text is held while the form is open; the system image picker may keep a temporary cached image.

Clearing business data or restoring a backup does not remove the secure installation UUID or latest support reference. On iOS, secure-storage values may survive reinstallation. Uninstalling is therefore not a promise that every MadeMargin-related value is removed.

05Photos you choose

You select individual images through the operating system’s photo picker. The app does not request broad access to your photo library for these flows. When you save a product, its chosen image is resized and saved as a JPEG copy in app-owned storage.

Product photos stay local unless they are included in a backup or export you choose to save or share. If you separately choose an image for a support request, that chosen attachment is sent when you submit the request.

Support attachments may contain embedded metadata within the image file. The support flow does not promise to remove it. Only attach an image whose contents and metadata you are willing to send. Removing an image from the support form does not delete the original from your photo library.

06Exports, backups, and sharing

You can explicitly create a backup, export materials, products, or sales as CSV files, and generate PDF reports. These files are created on your device. A MadeMargin backup includes business records, supported preferences, and available product photos; it does not include the secure support identifiers.

A backup is a readable file, not an encrypted vault. Anyone who can open the file can read its contents. Keep backups, CSV files, and reports somewhere you trust.

The operating system’s file and sharing tools let you choose a destination, such as device storage, a cloud drive, email, or a messaging app. Saving to a cloud service or sharing a file sends its contents to that destination. The receiving service and anyone you share with handle the file under their own practices.

Restoring a backup replaces the app’s business records and supported preferences after confirmation. A safety copy of the previous records is kept locally so you can undo the restore. MadeMargin does not automatically sync exported files or control copies saved outside the app.

Operating-system backups are separate from MadeMargin’s manual backup feature and depend on device settings and platform behavior. A local app record may also exist in a device backup; do not assume the app’s Clear data feature removes those copies.

07Retention and deletion

Local business records stay in app-owned storage until you remove them, use Clear data, replace them through a backup restore, or the operating system removes that storage. You can edit or delete individual records in the app.

When it succeeds, Clear data removes business records and attempts to remove app-owned product images, the restore safety copy, temporary export files, and preferences. The app reports incomplete cleanup. A copy retained in a saved product recipe, sales record, or backup is separate from the original record; deleting that original does not necessarily remove every saved copy of its details.

Clear data does not remove secure support identifiers or the latest support reference. It also does not delete a support request already sent, an email conversation, a file saved outside the app, or a copy held by a destination you chose. Manage those files or copies through the device or service where you saved or shared them.

Submitted support information may be kept for as long as reasonably needed to respond to the request, investigate issues, prevent abuse, meet applicable obligations, and maintain necessary support records. This policy does not specify a fixed retention period or a guaranteed deletion deadline.

You can request deletion of information you submitted to support by emailing the address in Privacy enquiries below. Limited records may need to be kept for applicable legal obligations or claims, security, abuse or fraud prevention, or necessary correspondence showing that a request was handled. Only information needed for that purpose is kept, and it is removed when the purpose no longer applies.

Delete your MadeMargin data

08Security

Business records and product photos use the app’s local storage. The installation UUID and latest support reference use operating-system secure storage. Support submissions are sent over HTTPS.

Local storage does not mean that all business data or exported files are encrypted by MadeMargin, and HTTPS does not provide an end-to-end encryption guarantee. Protect your device, its unlock method, and any files you export. No storage or transmission method can guarantee absolute security.

09The MadeMargin website

The website at https://mademargin.syedshahbazhussain.com is separate from the Android and iOS apps. It serves informational pages and does not read business records, photos, preferences, or secure identifiers from your installed app.

The website code includes no analytics or advertising scripts, account system, contact form, tracking cookies, or browser storage. Fonts and brand images are served with the site. An email link opens your chosen email application; any email you send is handled by the services used to deliver and receive it.

The website hosting provider is Vercel. Visiting the site sends technical request information to its hosting infrastructure, which may include an IP address, requested URL, request time, browser or device information, and referring page. The host may process traffic and infrastructure logs to deliver and secure the site. This is separate from advertising or analytics code in MadeMargin’s pages.

The hosting provider’s infrastructure practices and the website project’s logging settings must be checked separately. This draft does not claim that the host collects nothing or assign an unverified log retention period or processing country.

10Privacy enquiries and requests

For questions about this policy or to request deletion of submitted support information, contact Syed Shahbaz Hussain at the privacy and support address below.

For a support-data request, identify MadeMargin and include the email address used for your support submission. If available, include the request reference and approximate submission date so the relevant request can be located. Do not send a full business backup or an identity document unless it is needed and specifically requested.

The publisher cannot retrieve business records that remain only on your device. Use the app’s record controls, exports, and Clear data feature to manage that local information. Requests concerning information held by the support service are separate from local clearing.

11Policy updates

This page will be updated when MadeMargin’s data practices change, and the effective date will be revised. The draft notice will be removed only after the outstanding publication details are resolved. Check this page for the current policy.
