How can I set pages I built so that our clients can only see their entered data?

Hello James,

John’s statements regarding Skuid are correct. Skuid honors all Salesforce privacy/security settings, so there may be a rule somewhere allowing users to see other records.

That said, there is also the option to add a “lookup filter” to the reference field. By using a lookup filter you can limit the records available in the reference. Depending on how these users are related to the accounts, this may be an option as well. Please see the linked Skuid Doc on this.

Hope this helps!
