Everything that applies to the Bellwise app, in one place.
Last updated: 26 August 2026 · Version 1.0
The controller within the meaning of Art. 4 (7) GDPR for the Bellwise iOS application is HBJ-Solutions GbR, Haardter Str. 13, 67433 Neustadt an der Weinstraße, Germany (see Imprint).
Bellwise processes only the content you enter yourself: your subjects, teachers, rooms, lesson times, timetable entries and — with Bellwise Pro — your homework tasks and exams.
This content is stored exclusively in the app's private container on your device. It is not transmitted to us, not transmitted to any third party, and not synchronised to any cloud service by Bellwise.
Accordingly, in the App Store privacy questionnaire Bellwise is declared as “Data Not Collected”.
If you enable lesson reminders (a Bellwise Pro feature), the app asks iOS for permission to
show notifications and then schedules them locally on your device using
UNUserNotificationCenter. No push server is involved and no data leaves your
iPhone. You can revoke the permission at any time in iOS Settings → Notifications.
The Home Screen and Lock Screen widgets read your timetable from a shared app group container on the same device. This is a purely local mechanism.
Bellwise Pro is a one-time in-app purchase handled entirely by Apple. Payment is processed by Apple; we never receive or see your payment data. The app only queries Apple's StoreKit framework on your device to determine whether the purchase exists for the signed-in Apple Account. Apple's own handling of this transaction is governed by Apple's Privacy Policy.
As the seller, we receive aggregated, non-personal sales reports from Apple (for example "number of units sold per country per day"). These reports do not identify individual users.
The "Export backup" function writes a plain JSON file to a location you choose (for example Files, iCloud Drive or another app). Bellwise does not upload this file anywhere. Once the file leaves the app, the privacy policy of the destination you chose applies.
To the extent that the local processing of your entries constitutes processing within the meaning of the GDPR at all, it is carried out on the basis of Art. 6 (1) (b) GDPR (performance of a contract — providing the app's functionality you requested). Because no personal data is transmitted to us, we hold no personal data about you.
Your data remains on your device until you delete it. You can remove all app data at any time via Settings → Delete all data inside the app, or by uninstalling Bellwise, which removes its container and all contents.
Under the GDPR you have the right to information (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object (Art. 21), as well as the right to lodge a complaint with a supervisory authority (Art. 77). Because we do not store any personal data about you on our systems, we are generally unable to identify you or to provide information beyond this policy. You can exercise full control over your data directly in the app.
Bellwise is suitable for users of all ages and is designed for school students. Since the app collects no data at all, no special processing of children's data takes place.
We may update this policy when the app changes. The current version is always available at this address, with the date shown at the top of the page.
These terms govern your use of the Bellwise iOS application ("the App") provided by HBJ-Solutions GbR ("we", "us"). By downloading or using the App you accept these terms.
We grant you a non-exclusive, non-transferable, revocable licence to use the App on Apple-branded devices that you own or control, in accordance with the App Store Terms of Service and Apple's Licensed Application End User Licence Agreement (EULA), which is available at apple.com/legal/internet-services/itunes/dev/stdeula/. Where those terms and these terms conflict, Apple's Licensed Application EULA prevails.
Bellwise Pro is a one-time, non-consumable in-app purchase. It is not a subscription, it does not renew and it is not billed again. It unlocks the additional features described in the App at the time of purchase.
The purchase is bound to the Apple Account used to buy it and can be restored on any device signed in with that account via Settings → Restore purchase. Family Sharing is not enabled for this purchase.
Consumers in the European Union have a statutory right of withdrawal for distance contracts. For purchases made through the App Store, Apple is your contractual counterparty for the transaction, and refunds and withdrawal are handled by Apple. Requests can be submitted at reportaproblem.apple.com.
You agree not to reverse engineer, decompile, modify or redistribute the App, except to the extent such restriction is prohibited by applicable law.
Because Bellwise stores everything locally and does not sync to any server, we cannot recover your timetable if you lose your device, delete the App or reset your phone. Please use the export function to keep your own backup.
The App is a planning aid. We make no warranty that the times, rooms or reminders it displays are accurate — the content is what you entered, and reminders depend on iOS delivering them. Do not rely on the App as your only source for exam or lesson times.
We are liable without limitation for damages caused intentionally or by gross negligence, for injury to life, body or health, and under the German Product Liability Act (Produkthaftungsgesetz). In cases of slight negligence we are liable only for breach of a material contractual obligation (an obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose observance you may regularly rely), and in that case limited to the foreseeable damage typical for this type of contract. Any further liability is excluded. Statutory consumer rights remain unaffected.
Apple is not a party to these terms and has no obligation to furnish maintenance or support for the App. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of habitual residence.
We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).
