ShopWise is developed by Sami Studio (Miguel Fontes). Contact for privacy questions: suporte@samistudio.work.
We do not process data on the basis of consent, we show no ads, we do not sell data and we use no usage analytics tools.
Even without analytics, running the service involves processing some technical data:
The database and server functions are in the European Union. Some providers or services (Firebase Authentication, the hosting content delivery network, Google Fonts and Resend) may process data outside the European Economic Area, in particular in the USA. In those cases the transfer is covered by the safeguards provided for in the GDPR: the EU-US Data Privacy Framework where the provider is certified, or the European Commission's standard contractual clauses included in those providers' data processing agreements.
When you share a list, participants see the list name, its items and the owner's email. The owner and managers see participants' emails. If the owner deletes the list or the account, the list is no longer available to anyone, the purchases recorded in it are deleted and invite links stop working. If a participant deletes their account, they leave the list without changing the owner's data.
In offline mode, your shopping lists and related data are stored locally on your device and are not sent to our servers. If you choose to sign in and migrate your local data to your account, the selected data will be uploaded and synchronized through our cloud services.
We keep data for as long as the account exists. You can delete the account and all associated data in the app (Settings → Account → Delete account) or by email, as described in Delete account. After deletion your data is no longer in our active systems; technical logs and providers' backups may remain for a limited time, as described on that page.
Under the GDPR you have the right of access, rectification, erasure, restriction of processing, portability, and to object to processing based on legitimate interest. As we do not process data on the basis of consent, there is no consent to withdraw.
To exercise these rights, email suporte@samistudio.work stating the right you wish to exercise and your account email. To protect your account, we always confirm the request through the account's email address before acting. Exercising your rights is free, and we reply within one month, extendable by two further months for complex requests, in which case we will let you know. You can delete your account directly in the app, and correct or delete your lists' contents at any time.
You also have the right to lodge a complaint with the Portuguese data protection authority (CNPD, www.cnpd.pt) or the supervisory authority of your country.
