In short. Project Null0 builds several small software products. We keep the amount of personal information we hold to what each product actually needs to work. We do not sell personal information and we do not use it for advertising profiles. Payment card details never reach us — they are handled by Apple, Google or Stripe.
Project Null0 ("Project Null0", "we", "us") is a small independent software studio based in Poland. We are the controller of the personal information described in this policy.
This policy applies to every product and website we operate, including:
Some products publish their own policy with additional detail specific to that product. Where a product-specific policy exists, it applies alongside this one, and the product-specific document governs on any point where the two differ.
Several of our products are designed to work without an account. In that mode, the content you create is stored on your own device and is not sent to us. Uninstalling the application removes that local data.
When a product requires or offers an account, we handle the identifiers needed to sign you in and keep the account secure. Depending on the product and the sign-in method you choose, this can include your email address, a display name, a profile image you upload, the authentication provider you used, and an internal user identifier.
Where you sign in with Google or Apple, we receive the identifiers those providers release to us. We never receive your password for those accounts.
This is the material you put into a product: tasks, projects and habits in Radar, business and review data in RateCollector, files you upload, and anything you write in free-text fields. We process it in order to provide the product to you. We do not use your content to build advertising profiles.
If you enable cloud sync or connect a permanent account, your content is stored under your account identifier so it can be restored on your other devices. Deletion markers are kept so a device that has been offline does not silently recreate something you deleted.
We handle the information needed to know whether a subscription is active: the product purchased, the store or channel it came from, the purchase and renewal dates, trial eligibility, and the current entitlement state. This lets a subscription bought on one platform unlock the product on the others.
We never receive or store your card number, bank details or billing address. Payments are taken by Apple, Google or Stripe under their own terms and privacy policies.
If you contact us or send feedback from inside a product, we receive your message, any screenshot you deliberately attach, and basic technical details about the device and app version so we can reproduce the problem.
Our servers and our providers record ordinary technical data such as IP address, timestamps, request outcomes and error diagnostics. We use this to operate the services, investigate faults, and prevent abuse.
On iPhone and Android you can use the app without connecting an email, Google or Apple account. The app may create a pseudonymous identity so it can sync data under an identifier that is not linked to your name. The browser app is different: it opens only after you sign in with a permanent Google or email/password account.
RateCollector includes AI-assisted generation of review content. Text you submit for that purpose is sent to our AI provider to produce a result and is returned to you. We do not use your submissions to train third-party models.
Some of our apps transform images you provide. Those images are processed to produce the result and are not retained beyond the time needed to process them.
Where we rely on consent — for example an optional device permission — you can withdraw it at any time in your system settings, without affecting processing that already took place.
We use a small number of established providers. They act on our instructions and may process information only to deliver their service to us.
Some providers operate outside the European Economic Area. Where information is transferred internationally, it is done under an appropriate safeguard such as the European Commission's standard contractual clauses or an adequacy decision.
We do not sell personal information and we do not share it for advertising. We disclose information only:
We keep personal information only as long as it is needed for the purpose it was collected for.
You can delete your account from within the product where that option is offered, or by writing to us. Deleting an account removes the data held under it. Deleting an account does not cancel a subscription — a subscription must be cancelled in the store or channel where it was purchased.
Data in transit is encrypted. Access to stored data is scoped to the account that owns it, and our backend enforces those boundaries rather than relying on the client application. Administrative access is limited to what is needed to operate the services. No system is perfectly secure, but we take these measures seriously and act promptly if something goes wrong.
Subject to the conditions in applicable law, you may ask us to give you a copy of your personal information, correct it, delete it, restrict or object to how we use it, or provide it in a portable format. You may also withdraw consent where our processing relies on it.
To exercise any of these, write to contact@projectnull0.com. We answer within the period the law allows. If you believe we have handled your information improperly, you may complain to your local data protection authority; in Poland this is the President of the Personal Data Protection Office (UODO).
Our products are not directed at children who are below the age at which they can consent to online services in their country, and we do not knowingly collect their personal information. Products aimed at a family audience state their own age handling in their product-specific policy. If you believe a child has provided us with personal information, contact us and we will delete it.
We update this policy when our products, providers or legal obligations change. The revision date at the top always reflects the current version. Where a change materially affects you, we will give notice in the product or by email.
