No advertising business
We do not sell personal information, build advertising profiles, or share your activity with marketing companies.
Your library is yours.
Addendo is built to remember things for you—not to learn things about you. Your private library stays inside the service and is used only to provide the features you choose.
Last updated 25 August 2026Private by default
Saved items and collections begin private. They become visible to other people only when you deliberately invite someone or publish a collection.
Only what the product needs
We keep the account details, preferences, and library information required to run Addendo. We do not collect data simply because it might become useful later.
01
How your information is used
Your information is used to authenticate your account, save and organize your library, provide search and classification, maintain security, and support features you request. It is not repurposed for advertising or unrelated commercial profiling.
02
Essential services
If you choose Google or Microsoft sign-in, that provider handles the sign-in exchange. If you purchase a plan, Paddle handles payment and billing information. Addendo sends only what is necessary to complete the service you requested; private library contents are not shared with these providers.
03
Your choices
You control what you save and share. You can export your information, make collections private, remove library items, or delete your account from Settings. Deletion is intended to be deletion—not a change of label.
04
Using Addendo responsibly
Each account is for one person. Do not share credentials, operate one account for multiple people, circumvent plan limits, interfere with the service, or use automation in a way that harms Addendo or others.
Do not use Addendo to store, organize, publish, or distribute links to material whose possession or distribution is unlawful. Serious or deliberate violations may result in an immediate and permanent account ban, including loss of access to stored content.
05
Operator and contact
Addendo is operated by Bert Sanchis. For privacy questions, access or deletion requests, or other support, email support@addendo.org.
