Privacy Policy

Effective date: 10 June 2026  |  App: MostBuilder — Quick Estimate  |  Developer: Muhammed Baki Yucel, Baki Mega

The short version

What we actually collect

Honestly? Almost nothing by design.

When you use MostBuilder, you may voluntarily send:

• Chat messages — the text you write when describing your renovation task.
• Attached photos — images you select to give the assistant visual context for your project.

That is the complete list of user-provided content. We do not ask for your name, email address, phone number, home address, payment details, or any other personally identifiable information within the app itself.

For technical operation, the app may generate or receive a unique device identifier. This anonymous ID exists solely to support push notification delivery and basic usage analytics. It cannot be used to identify you as a person, and it is not linked to any personal profile we maintain — because we do not maintain one.

What we deliberately do not do

• We do not operate a social network. Users never exchange data with one another.
• We do not sell, rent, or trade any information — there is scarcely any to trade.
• We do not use your photos for advertising, facial recognition, or training unrelated models.
• We do not track your location, contacts, calendar, or other device data beyond what is described here.

Third-party services

MostBuilder relies on a small number of external providers to function. Each operates under its own privacy policy, and we encourage you to review those documents independently.

OpenAI — a third-party artificial intelligence service used to generate renovation estimates and planning advice. When you send a chat message or attach a photo, that content is transmitted to OpenAI's servers for processing. OpenAI receives only the text and image you submit — no name, no account credentials, no contact details. OpenAI's handling of this data is governed by their own privacy policy at openai.com/policies/privacy-policy.

Singular — a third-party attribution and analytics platform. Singular may receive the anonymous device identifier mentioned above to measure how users discover the app. No personal content from your chats or photos is shared with Singular.

OneSignal — a third-party push notification service. OneSignal uses the anonymous device identifier to deliver notifications you have opted into, such as reminders or app updates. No chat content or photos are transmitted to OneSignal.

How your content is used

Text messages and photos exist for one purpose: generating your renovation estimate inside the app. They are processed by the AI service, displayed back to you as planning results, and stored locally as part of your project history on your device. We do not repurpose your renovation descriptions for marketing, profiling, or resale.

Data retention

Project history is stored on your device and remains there until you delete it or uninstall the app. We do not operate a central database of your renovation plans tied to your identity. Content sent to OpenAI for processing is subject to OpenAI's own retention practices.

Children

MostBuilder is intended for adults planning home improvement projects. We do not knowingly collect information from anyone under the age of 13. If you believe a child has used the app in a way that concerns you, please contact us and we will address it promptly.

Your choices

You control what you share. Do not attach photos you are uncomfortable sending. You can delete individual project histories within the app, disable push notifications in your device settings, and uninstall the app at any time to remove locally stored data.

Changes to this policy

We may update this document as the app evolves. When we do, the effective date at the top will change. Continued use of MostBuilder after an update constitutes acceptance of the revised policy.
