Privacy Policy

Nothing, unless you choose to send it. Cortex Solution runs no server, holds no accounts and receives nothing automatically from Mellie — there is no telemetry and no analytics, so nothing about your use of the app reaches us on its own.

There is one exception, and it only happens when you decide it should: if you report an AI suggestion (see below), Mellie prepares an email for you containing that suggestion and the task you typed. You see the whole thing before it is sent, you send it yourself from your own mail app, and if you change your mind nothing leaves. What we then hold is an email you chose to send us, which we use only to look into what you reported.

Everything Mellie holds, it holds on your PC, and you can see exactly where in Settings → Your data, which shows both the database and the log folder.

Tasks and projects are kept in a single database file inside the app's own data folder. Titles and notes are free text, so they contain whatever you write — which may well be personal. That text is yours and stays where you put it.

That file is not encrypted. It relies on the file permissions Windows already applies to your user account, the same protection as any other document on your PC. Anyone who can sign in as you, or who has physical access to an unlocked machine, can read it. If that matters for your situation, use full-disk encryption such as BitLocker.

Only if you choose to use the AI planner and paste in a key of your own. It is stored through Windows Credential Manager — never written to a settings file, never into the task database, and never written to a log.

It is used for one thing: authorising the requests you trigger, against your own account with the provider.

When something goes wrong, Mellie writes a line to a log file beside the database — the time, the type of error, its message, the stack trace, and the app and Windows versions. The file rotates, keeping three generations.

It is never uploaded, and there is nowhere for it to go. We would rather say one more thing than one fewer: an error message could in principle include a fragment of your own task text, because that is sometimes what the app was working on when it failed. The log stays on your machine either way, and deleting the app data folder removes it.

Mellie files most tasks using rules that run on your own machine. When its confidence in a task drops below 65% — or on every task, if you ask it to — it can send that one task to an AI provider to be classified. This only happens once you have switched the planner on and supplied your own API key.

The request goes from your machine straight to the provider, authorised by your key and billed to your account. It does not pass through any server of ours, because we do not have one. By default that provider is OpenAI, and the address is configurable if you point Mellie at something else.

Whoever receives it is an independent controller of what you send, under their own terms and privacy policy — not ours. OpenAI's is at openai.com/policies/privacy-policy.

Turning the planner off stops it. Removing your key stops it too, and the rules carry on working exactly as before.

Mellie ships with one AI mode: your own API key. There is no second path, and nothing on your machine is driven on your behalf.

Anything the AI planner writes can be reported, from a link on the suggestion itself or from Settings. It is the only way to tell us an AI suggestion was wrong or inappropriate, and the Microsoft Store requires products with generative AI to offer it.

A report contains the task sentence you typed, the fields the AI produced from it, its written reasoning, the reason you picked and any comment you added, plus the app version and the time.

Mellie writes that report to a file on your machine first, then shows it to you in full and offers to open your email app with it ready to send. Mellie never sends it. You do, or you do not — and if you do not, the local copy simply stays on your machine with everything else.

Speech recognition uses the recogniser built into Windows and runs on your device. Audio is never recorded to a file and never transmitted. The words it hears land in the input box for you to check before they become a task.

The microphone is only listened to while you are pressing the microphone button.

So that Mellie reappears where you left her, the app remembers her position per display. Those saved settings include the device names Windows gives your monitors and the size of each work area.

It is information about your machine rather than about you, it sits in the Windows preference store with the rest of your settings, and it never leaves the PC. It is listed here rather than folded into the word “settings” because you should not have to guess what a setting contains.

Microsoft distributes the app through the Store and provides the speech recogniser, which runs locally. Their handling of your Store account is between you and them and has nothing to do with what is inside Mellie.

Your AI provider, and only if you enable the planner and supply your own credentials.

That is the entire list. There are no analytics providers, no advertising networks, no crash-reporting services, no content delivery networks and no payment processors.

There is no server-side retention period, because there is no server. Your data lasts exactly as long as you keep the folder it is in.

Uninstalling Mellie, or deleting the app data folder, removes the tasks, the settings and the logs. Both paths are shown in Settings → Your data.

There is no backup and no recovery. We cannot restore your tasks, because we never had them. If the file is lost, it is gone.

Mellie is suitable for all ages and is not directed at children. It collects nothing from children for the same reason it collects nothing from anyone: there is no collection.

Rights to access, correct, export or erase personal data assume somebody is holding it. Nobody here is. Your data is already in your possession, already editable, and already deletable by you alone.

If you send us an email we will of course have that email, and we will use it only to answer you.

If Mellie ever gains a feature that changes what leaves your machine, this page changes first, and the date at the top of it changes with it.
