Terms of Service
These Terms of Service ("Terms") govern the Tefteri mobile app, including its local notebook features and optional online sync service (together, the "Service"). Please read them before using the Service. If you do not agree, do not use the Service. Connecting your notebook with Google signifies acceptance of these Terms, as explained beside the sign-in action in the app. Acceptance of these Terms is separate from consent to personal-data processing. This version applies from publication, subject to the protections for existing users in section 16.
1. Who We Are
Tefteri is operated by Pavlos Stathopoulos as an individual, based in Athens, Greece. References to "we", "us", or "our" mean Pavlos Stathopoulos; "Tefteri" is the app's name. Tefteri is a personal notebook for tasks, scheduled reminders, dated entries, categories, and related notes.
2. Eligibility
Tefteri is intended for people aged 15 and older. You must be able to enter into these Terms under the law that applies to you. If you are a minor and cannot do so independently, your parent or legal guardian must review and agree to these Terms on your behalf where local law permits. The minimum age is our audience policy; it does not override local rules on contractual capacity or consent to personal-data processing.
3. Local Use, Accounts, and Security
- You can use the notebook locally without an account.
- Optional cloud sync uses Google Sign-In through Firebase. Connecting a local notebook combines it with that account's synced notebook and binds it to that account. Signing out stops authenticated sync but does not remove that binding or erase local data. Connecting the same notebook to a different account is not supported; you can export it and start fresh on that device instead.
- Take reasonable steps to protect your device and Google account. You are responsible for your own use of the Service, but these Terms do not make you automatically liable for unauthorized activity beyond your control.
- If you suspect unauthorized account access, contactsupport@pavlossta.com.
- You can delete a signed-in account in the app after Google reauthentication, or request deletion without app access through theAccount Deletion page.
4. Acceptable Use
You must not:
- Use the Service unlawfully or infringe another person's rights.
- Access another person's account or data without authorization.
- Interfere with the Service's operation, bypass security controls, or abuse hosted resources.
- Reverse engineer or extract software except where applicable law or a licence permits it.
These restrictions do not prohibit normal personal use, the app's export feature, or activity permitted by law. Restrictions on hosted access are addressed in section 12.
5. Your Content
- You retain ownership of your entries, reminders, categories, and notes.
- When you enable sync, you grant us a non-exclusive, royalty-free permission to host, store, transmit, and process your synced content solely to provide the Service to you. This permission does not allow us to sell your notebook content or use it for advertising. It lasts only as needed to provide the Service and complete deletion, subject to lawful retention described in the privacy documents.
- Content kept only in the local notebook is not uploaded as notebook content unless you connect it for sync. This does not mean the app has no other network activity; see the Privacy Policy for technical and usage-data processing.
- You are responsible for the content you enter and for having the rights or permissions needed to use it. If it includes another person's data, comply with applicable law and respect that person's rights.
- Tefteri is a general-purpose personal notebook, not a healthcare service. We do not request health information or other special-category personal data. You must not enter, synchronize, or send us sensitive personal data about yourself or others. This includes health information, racial or ethnic origin, political opinions, religious beliefs, trade-union membership, genetic data, biometric identification data, sex life or sexual orientation, and criminal convictions or offences. The prohibition applies to local entries, synchronized content, support messages, and feedback. The app does not inspect or automatically classify your notes. If you believe you have uploaded sensitive information, delete the relevant content and contact privacy@pavlossta.comfor assistance. See the Privacy Policy for information about data handling.
6. Reminders and Professional Advice
Tefteri is an organizational tool. It does not provide medical, legal, financial, or other professional advice. Seek qualified guidance when needed.
Notifications depend on device permissions, operating-system settings, and device availability. They can be delayed or fail to appear. Do not rely on Tefteri alone for emergencies or critical deadlines; use an appropriate additional reminder method. These practical limitations do not remove your statutory rights.
7. Price
The Service is currently free of charge. If paid features are introduced, their price, payment conditions, and applicable purchase terms will be disclosed before you choose to purchase them. We will not charge you merely because you already use the app.
8. Privacy and Deletion
Our Privacy Policy andData Protection Notice explain personal-data processing and your rights. Accepting these Terms does not constitute consent to all processing described in those documents. Where consent is the required legal basis, it must be obtained separately and can be withdrawn as explained in the privacy documents. Account and data deletion options are explained on theAccount Deletion page.
9. Intellectual Property
Rights in the app's original software, design, text, and graphics belong to Pavlos Stathopoulos or the relevant rights holders. You may use the app for its intended purpose. Your notebook content remains yours. Third-party components remain subject to their own licences, including any open-source licences; these Terms do not restrict rights granted by those licences or by applicable law.
10. Third-Party Services
Optional authentication and sync depend on Google and Firebase. Features that interact with other services may also be subject to those providers' applicable terms. We do not control their availability, but using third-party providers does not remove our own contractual or data-protection responsibilities. Provider and data-processing details are described in the privacy documents.
11. Availability, Changes, and Keeping a Copy
Local notebook features are designed to work offline. Online sync requires a connection and access to the connected account. Neither uninterrupted cloud availability nor error-free operation is guaranteed.
We may change the Service for valid reasons, including security, legal requirements, maintenance, compatibility, or improvements. Changes will respect applicable consumer rights. For material changes that adversely affect access or use, we will give reasonable advance notice and explain available options, including any legally required right to terminate. Urgent security or legal measures may require immediate action.
For a planned discontinuation of cloud sync, we will notify connected users in advance by account email and provide a reasonable opportunity to sync and export their notebook. Ending hosted access does not itself erase data already stored locally on a device.
Use Profile → Export data (Εξαγωγή δεδομένων) to save or share a JSON copy of the active notebook stored on your device, including local changes. Cloud sync is not a guaranteed backup and is not a substitute for keeping an independent copy of important information.
12. Stopping Use and Account Termination
You may stop using Tefteri at any time. Uninstalling the app does not delete your Firebase account or synced cloud notebook. Signing out does not delete your account, cloud data, or local notebook. To delete the account and associated data, use the in-app deletion action or the email-request route on theAccount Deletion page. Starting fresh on a device clears readable records belonging to that notebook locally without deleting its cloud data. Unreadable recovery data with unknown ownership may remain; Android app-storage clearing removes remaining installation data.
We may restrict or terminate hosted access for a material breach of these Terms, a security risk, or a legal requirement. Measures will be proportionate. Unless security or law prevents it, we will explain the reason, give an opportunity to address the issue, and allow you to contact support to contest the decision. Where lawful and feasible, we will provide an opportunity to export before permanently ending hosted access. Suspension of hosted access does not itself erase your local notebook.
Provisions concerning ownership, lawful retention, and resolving an existing dispute continue only to the extent relevant after termination. Your statutory rights remain unaffected.
13. Reliability and Your Rights
We take reasonable care in providing Tefteri, but software, devices, and networks can fail. We cannot promise that every notification will appear, every sync will finish immediately, or data will never be lost. Nothing in these Terms excludes any guarantee, remedy, or other consumer right that applicable law does not allow us to exclude.
14. Liability
Our liability is determined by applicable law. Nothing in these Terms excludes or limits liability for fraud, intentional misconduct, gross negligence, death or personal injury where such liability cannot be excluded, or any other liability that cannot lawfully be excluded or limited. Your mandatory consumer and data-protection rights remain unaffected.
15. Governing Law and Disputes
These Terms are governed by Greek law. If you are a consumer, this choice does not deprive you of mandatory protections under the law that would otherwise apply, including relevant protections of your country of habitual residence. You may bring a claim before any court that has jurisdiction under applicable law, including courts where you live when consumer jurisdiction rules provide that right. These Terms do not require exclusive proceedings in Athens or restrict your right to contact a competent authority.
16. Changes to These Terms
We may revise these Terms for changes in the Service, legal requirements, or to clarify their wording. Each revision has a version date. Material changes affecting connected accounts will be notified by email to the address associated with the account before they take effect, with a summary, effective date, and link to the revised Terms. Urgent changes required by law or security may take effect sooner, with notice as soon as possible.
You can decline revised Terms by stopping use of the affected service and, if you wish, exporting your notebook and requesting account deletion. New contractual obligations will not apply retroactively. For local-only users, material changes apply only after they have been made available and any acceptance required by law has been obtained. Where affirmative acceptance is required, an update to this page or continued use alone will not replace it. Changes to these Terms never constitute consent to personal-data processing.
