SpaceApp Privacy Policy
Last updated: 1 November 2026
This policy covers SpaceApp, the Arcbazar app for iPhone and Android. It explains what the app collects, why, who helps us run it, and the choices you have. The website arcbazar.com has its own privacy policy.
Who we are
SpaceApp is made by Arcbazar.com, Inc. ("Arcbazar", "we", "us"), Harvard Innovation Lab, 114 Western Ave, Allston, MA 02134, USA. Questions: support@arcbazar.com.
Using the app without an account
You can look around without signing up: explore completed projects, top designers and designer profiles. The app then uses an anonymous session that is not linked to your name or e-mail address.
What we collect
- Your account: your name, e-mail address and password (handled by Google Firebase Authentication; we never see the password). If you continue with Apple, Google or Facebook, we receive your name and e-mail address from that service.
- Your profile: a profile photo and what you choose to write about yourself or your work.
- Your projects: the brief you write, photos and videos of your space, the award you set, and your ratings and comments on designs.
- Messages: messages with designers or clients, comments, and conversations in the Open Studio and in competition rooms.
- Open Studio: while you are in it, designers see your first name, your country (taken from your phone's region setting, not your location) and which kind of project you are looking at.
- Notifications: a device token so we can send the notifications you have switched on.
- Diagnostics: crash reports, performance data and which screens are used, through Google Firebase. These are not linked to your name and are not used for advertising.
We do not collect your precise location, your contacts, your browsing history or payment details. Payments for competitions are made on arcbazar.com.
How we use it
- To run your competition: show your brief to designers, show you their designs, and let you rank them.
- To let clients and designers talk, and to send the notifications you have switched on.
- To keep the app working and fix problems.
We do not sell your information, we do not show advertising in the app, and we do not track you across other apps or websites.
Designers stay anonymous
While a competition runs, clients see each design by its entry number only. Designers' names are shown after the client's final ranking.
Competition rooms and the project Wall
The competition room is a live conversation between the client and the designers while the competition runs. So that every designer has the same information, the conversation is posted to the project's Wall on arcbazar.com when the client leaves the room, where it can be read like any other Wall post.
AI features by Anthropic
SpaceApp offers optional AI features that help you judge and understand designs: Rank Projects with AI, comparing two designs, short case studies of completed competitions, and From design to reality, which compares a winning design with photos of what was built. These features are provided by Anthropic, PBC, an AI company acting as our service provider.
What is sent: only what the feature needs: the competition's title and brief, images of the designs and, for built projects, photos of the result. While you judge, your scores and your friends' scores may be included. Designs are identified by entry number only, never by the designer's name. We do not send your name, e-mail address, account details, messages, location or payment information.
Your choice: the app asks for your permission before it uses an AI feature for the first time. If you say no, the AI features stay off and everything else works as usual. You can turn them on or off at any time in Settings → AI features by Anthropic.
How Anthropic uses it: Anthropic processes this information only to return the answers to us, under its commercial terms, and does not use it to train its AI models. It keeps it only for a limited time, as described in Anthropic's privacy policy.
What we keep: the AI's written answers (not the images), so the same question is not processed twice: for 7 days for competitions that are still running, and up to one year for finished competitions, case studies and built projects. We also count AI requests per account per day to keep the service fair. AI answers are marked as such and can contain mistakes.
Descriptions of built projects are made from the competition's public information and photos of the finished result, and may be shown to other people in the app. To have one removed, write to us.
Who helps us run the app
These companies process information on our behalf, only to provide their service to us:
- Google Firebase: accounts, database, notifications, crash reports and app analytics.
- Amazon Web Services: storage of photos, videos and design files.
- Anthropic: the AI features, if you turn them on (see above).
- Apple: delivering notifications on iPhone, and Sign in with Apple if you use it.
- Google and Facebook: only if you choose to continue with them to sign in. Facebook's automatic app events and advertising identifier are turned off.
We may also share information when the law requires it, or with a company that takes over Arcbazar's business, under this policy.
The spaceapp.ai website
The website uses Google Analytics to count visits and see which parts of the page people use: pages viewed, clicks on the store badges and the FAQ, the site that sent you, and your approximate country and device type. Analytics cookies are set only if you choose Accept in the cookie bar. If you decline or don't choose, Google Analytics receives only cookieless signals without identifiers. You can change your choice at any time with "Cookie settings" at the bottom of the page. The website has no sign-in and no forms, and we don't use what it measures for advertising.
Your choices
- Notifications: switch each kind on or off in Settings.
- AI features: on or off in Settings.
- Your details: change your name, photo and password in Settings.
- Delete your account: Settings → Delete account removes your account and its data from our database. To also have your uploaded photos and files removed from our storage, or for any other request about your data, write to support@arcbazar.com. Without the app: ask us to delete your account.
Security
Information is sent over encrypted connections and kept on access-restricted servers. Photos and files are in private storage and shown only through the app. No system is perfectly secure, but we work to protect your information against loss and misuse.
Children
SpaceApp is not intended for children under 13, and we do not knowingly collect information from them. If you believe a child has given us information, write to us and we will delete it.
Changes
If we change this policy, we will post the new version here with a new date. If a change is significant, we will tell you in the app.
