FAQ
You can find the most important questions before you start here. For more support, there are two tools available in the app: Contextual help and Full Q&A
Context-sensitive help is available in every app section and can be accessed via the > ? < icon.
The complete Q&A, which contains all questions and answers, can be found in the app menu (without context link, but categorized).
Why does true-perfect-code follow such a strict anonymization approach?
The EU General Data Protection Regulation (GDPR) lays down strict guidelines for the handling of personal data, non-compliance with which can have serious consequences, especially for smaller companies. However, our approach goes beyond mere compliance with legal regulations: by consistently anonymizing data, we ensure that personal data is not stored by us in the first place. This not only protects us, but more importantly, it protects you - because even in the unlikely event of a server attack, your data remains secure and cannot be misused.
How can I be sure that my data under my app account is really anonymized?
Quite simply because registration in the app is possible without email or verification. So if you choose a random account name, the data collected cannot be assigned to you personally as we do not know who you are.
Do I have to pay to use the software?
There is no obligation to pay for the use of the software, but we are happy to receive a voluntary donation (link in the app) to maintain development and operation. This way, the app remains anonymous and ad-free.
I am registered via an external provider and have logged out of the app for security reasons. Now, when I have no internet, I cannot access my data because it is not possible to log in again via an external identity provider.
If there is no internet and a local account has been created via an external ID provider, the user must not log out beforehand, otherwise they will not be able to access the app. There are technical reasons for this, because if the app has no internet connection, it has no way of authenticating the user via an external identity provider. The alternative is that you do not log out of the app or that you create your own app account, because then a local login is possible as the user can be authenticated via the local database on the device.
What do I need to keep in mind when activating two-factor authentication (2FA)?
After activation, you will receive a QR code for your Authenticator app and a backup code to reset 2FA even if you lose your device.
I have suggestions for software enhancements, will they be implemented if I report them?
You are welcome to send us your suggestions. Please note, however, that we not only develop our own software, but also complex software solutions on behalf of other customers. We must therefore check on a case-by-case basis whether the further development of software financed by donations is still financially viable for us.

Understanding pTodo:
Question: Do I have to pay to use the software?
Answer: There is no obligation to pay for the use of the software, but you should consider contributing to the development and operation of the software once a year in the form of a small donation. This is the only way we can enable you to use the software anonymously and without advertising.
Question: Why does true-perfect-code place so much emphasis on anonymizing user data?
Answer: As a company, protecting your data is particularly important to us. The EU General Data Protection Regulation (GDPR) sets strict guidelines for handling personal data, non-compliance with which can have serious consequences, especially for smaller companies. However, our approach goes beyond mere compliance with legal requirements: Through consistent anonymization, we ensure that personal data is never stored by us in the first place. This protects not only ourselves, but, more importantly, you – because even in the unlikely event of a server attack, your data remains secure and cannot be misused. For us, data protection is not a necessary evil, but a conscious decision for greater security and trust.
Account & Data:
Question: What to look out for when activating two-factor authentication (2FA)?
Answer: If you activate 2FA, you will receive a one-time QR code as well as a backup code that you can copy away. The QR code is used to install 2FA on your device. The installation takes place in an authentication app (e.g. Google Authenticator from the store). The app then continuously generates new 6-digit login codes for you every 30 seconds, which you can then use to authenticate yourself in our app for the second time (hence 2FA). If you lose your device or delete the Authenticator app, you can use the backup code to reset 2FA.
Question: I am registered via an external provider and have logged out of the app for security reasons. Now when I have no internet, I cannot access my data because it is not possible to log in again via an external identity provider.
Answer: If there is no Internet and a local account has been created via an external ID provider, the user must not log out beforehand, otherwise they will not be able to access the app. This is for technical reasons, because if the app has no internet connection, it has no way of authenticating the user via an external identity provider. The alternative is that you do not log out of the app or that you create your own app account, because then a local login is possible, as the user can be authenticated via the local database on the device.
Question: How can I be sure that my data is truly anonymized under my app account?
Answer: Quite simply because registration in the app is possible without email or verification. So, if you choose a random account name, the collected data cannot be assigned to you personally because we don't know who you are.
Question: How can I be sure that my data is actually anonymized under my external Google/Microsoft/Apple account?
Answer: Your data will be anonymized in this case as well, but the problem is that we can't prove it to you. Generally, we only require the user's authentication and their Open ID (sub-number) from the external identity provider (Google, Microsoft, or Apple), which we then store in our database in hashed form so that the app data can be linked to an account. Since we do not request the account name, email, or any other data from the external identity provider, your account data is anonymized even when logging in externally.
Troubleshooting & Error Messages:
Question: Saving neither on the cloud nor locally possible!
Answer: If this message appears, it is most likely a conceptual error in the app. It is best to try to reproduce the error and then send us a report.
Question: What does the message 'There are no categories' mean?
Answer: For some unknown reason, no categories have been created in your app. Without categories, todos cannot be created and therefore it is not possible to use the app. If this message appears, it is most likely a conceptual error in the app. It is best to try to reproduce the error and then send us a report.
Question: What does the message that there is no Internet connection mean?
Answer: Your device currently has no Internet Connection (the status of your Internet connection is displayed in the top right-hand corner of the app.). You may need to restart the app if an internet connection becomes available again. Please note that some areas of the app may not work without internet (e.g. registering new accounts).
Question: What does the message 'No timestamp of the account' or 'It could not be verified if a cloud account exists' mean?
Answer: The app can only be used if a valid account is registered in Cloud (either via an external identity provider or your own account in the app). If your client cannot determine this cloud account, the app will not be started (even if a local account may exist). This is an intentional implementation.
Question: What does the message 'A local account does not exist' mean?
Answer: If the app cannot create a local account, this error message will be displayed. If this message appears, it is either a restriction on your device or a conceptual error in the app. It is best to try to reproduce the error and then send us a report.
Question: What does the message 'The server does not provide a token' mean?
Answer: This message means that your device has not received an access token from our WebApi server (or token is invalid). This can happen for various reasons, e.g. the Internet connection is very poor or our WebApi server is down or overloaded. Try to use the app at a later time. If the situation does not improve, it is also possible (rather unlikely) that this is a conceptual error in the app. Reproduce the error and send us a report.
Question: What does the message 'Registration/login not possible. The client does not generate a unixts' mean?
Answer: For some reason, the local (or cloud) account could not be determined. It is most likely a malfunction of the app whose cause (whether restriction on the device or conceptual error in the app) can only be determined on the basis of your reports.
Question: What does the message 'Registration/login not possible. The user name already exists' mean?
Answer: You will receive this message if the account data record you are trying to save has already been created in the database. It is unlikely (although theoretically possible) that this is also a conceptual error in the app. It is best to try to register with a different account, which hopefully is not already in use.
Question: What does the message 'Categories could not be synchronized with the cloud' mean?
Answer: Your local and cloud categories are automatically synchronized in cloud/cloud-local storage mode. If this message appears, then something went wrong during synchronization and it is most likely a conceptual error in the app. It is best to send us a report.
Question: What does the message 'User settings could not be loaded' mean?
Answer: If this message appears, the app has a problem reading your settings. This is most likely a malfunction of the app. Please check whether the error is temporary (perhaps because our WebApi server is unavailable) or permanent and send us a report.
Question: What does the message 'Data could not be sent to web server because Json data is missing' mean?
Answer: This message indicates a connection problem with our WebApi server. Please check your internet connection and send us a report if the problem persists.
Suggestions & Feedback:
Question: I have suggestions for the software enhancements, will they be implemented if I report them?
Answer: You are welcome to send us your suggestions. However, please bear in mind that we not only develop our own software, but also complex software solutions on behalf of other customers. We therefore have to assess on a case-by-case basis whether the further development of software that is financed by donations is still financially viable for us.

Help: Login & Registration
This window is your access point to the app from the landing page. It offers you options for language selection and authentication.
Language Selection:
In the upper area you can choose the display language. Up to 10 of the most spoken languages in the world are available, identified by common country abbreviations.
- Special feature "BL": This abbreviation stands for the Balkan Peninsula (Ex-Yugoslavia) and is used neutrally, as we do not use a specific country designation due to the political situation.
- More/Less button: Toggles the display of additional languages on or off. By default, German and English are visible.
Authentication Options:
The app offers two ways to log in, which you can select via separate tabs:
- 1. External Identity Providers (Google, Microsoft, Apple):
We only ask for the general OpenID Sub-number (
sub) of your account. Although this number is already anonymized, we hash it additionally and store it in this form in our database. - 2. App-owned Account and Password:
Registration does not require an email address and can be done with any string as an account name. Before saving to our database, both the account name and password are hashed.
It is technically impossible for us to verify your identity based on the stored hash values or to derive your original login data. Your anonymity is thus fully preserved.
