SynthMaker · Privacy

Applies to SynthMaker for iPhone, iPad and Mac, and to the website synthmaker.com with the web app at synthmaker.com/app, published by ViDesk Ltd (the data controller). Last updated 29 October 2026.

Your sounds, songs and settings stay on your device or in your browser. Only the community, if you join it, keeps data on our server.

No tracking

The SynthMaker apps have no advertising, no analytics and no tracking. The website counts visits without cookies (see below). We don't sell or share your data for advertising, and we don't follow you across other apps or websites.

What stays on your device

• Your sounds, songs, clips, visuals and the videos you make. They live in the app's folder on your device (and in Files, if you open them there).
• Your settings, tutorial progress and choices such as which AI model to use.

None of this is sent to us. Videos you save go to your Photos library only when you choose to save them; the app asks for permission first. Like other app data, these files may be included in your own iCloud or computer backups, which Apple handles under its own privacy policy.

The website and the web app

• Hosting: synthmaker.com is served by Cloudflare. Like any web host, it handles technical information such as your IP address to deliver the pages and keep the site secure.
• Counting visits: we use Cloudflare Web Analytics to see how many people visit, which pages they open, which sites linked to us, the kind of browser and device, the country, and how fast pages load. It uses no cookies, stores nothing in your browser and isn't used to follow you across websites. We see totals, not individual visitors.
• The web app runs entirely in your browser, on SynthMaker's own engine. The sounds you play and the knobs you turn aren't sent to us. If you connect a MIDI keyboard, its notes stay in your browser. The web app remembers in your browser that you've read its beta notice; clearing this site's data in your browser removes that.
• Signing in on the website (optional): you can sign in with Apple or Google. We then keep an account ID, the email address your provider shares with us, and the name it shares (Google also shares a link to your profile picture). Sign in with Apple uses the same account as in the app. Your browser keeps you signed in until you sign out. You can delete the account on synthmaker.com/account, which deletes it everywhere.

The AI features (in the apps)

When you describe a change ("make it darker"), your request and the sound's settings go to the AI model you choose in Settings:

• Apple on-device: nothing leaves your device.
• Apple Private Cloud Compute (where SynthMaker offers it): processed by Apple under its Private Cloud Compute privacy guarantees; not stored and not available to us.
• Your own server (for example LM Studio on your Mac): sent only to the address you enter, under that server's terms.

We never receive your AI requests.

The community (only if you join)

Anyone can read the in-app community (Ask the developer and the chat) without an account. To post, you sign in with Apple, choose a name and accept the community rules. Then we keep:

• Your account: an account ID, and the email address Sign in with Apple shares with us. You can choose Apple's "Hide My Email", which gives us a private relay address instead of your real one. We use it only to run your account; we don't send newsletters.
• Your profile: the name you choose, which is shown publicly next to what you post.
• What you post: your questions, replies and chat messages, with the time they were posted. These are public: anyone using SynthMaker can read them.
• Safety records: reports you make (with a copy of the reported post), the accounts you block (visible only to you), and a log of when you post, used for rate limits.

We use this data only to run the community and keep it safe: to show posts, enforce the rules, review reports and prevent abuse. When someone posts a question or makes a report, a notification with that text and the author's name is sent to a private channel the developer uses for moderation (on Discord).

The legal bases are our contract with you (running the community you joined) and our legitimate interest in keeping it safe (moderation and abuse prevention).

Where it is stored

Community data is stored with our hosting provider, Supabase, on servers in the European Union (Ireland). Sign-in uses Apple's Sign in with Apple and, on the website, Sign in with Google. Like any server, ours records technical information such as IP addresses in short-lived logs for security and to keep the service running.

Deleting your account

In SynthMaker, open Community › your account › Delete account. After you confirm it's you, we delete your account, your profile and everything you posted. Your sounds and songs on your device are not affected. To also stop using Sign in with Apple with SynthMaker, open Settings on your device, tap your name, find Sign in with Apple, choose SynthMaker and tap Stop Using; the app shows you how.

A few safety records are kept, only as long as they are needed for moderation:

• reports you made about other people's posts, with your name removed;
• reports others made about your posts, with the copy of the reported post they include;
• if your account was banned for breaking the rules, a one-way fingerprint of your sign-in, so the ban still applies if you return.

Your rights

You can ask for a copy of your community data, ask us to correct it, or object to how we use it, by writing to us. You can delete your account yourself at any time in the app. If you are in the UK or the EU, you can also complain to your data protection authority (in the UK, the Information Commissioner's Office).

Children

The community is not meant for children under 13, and we don't knowingly collect data from them. If you believe a child has joined, write to us and we'll delete the account.

Changes

If this policy changes, we'll update this page and the date above, and tell you in the app or on the website if the change is important.
