Parties, appointments and task assignments often require less personal information than people initially assume. A well-designed shared list collects only what helps with the immediate decision. This keeps the table clear and limits the consequences if its link is accidentally forwarded.

This guide offers practical orientation rather than legal advice. Professional, official or particularly sensitive information may be subject to additional requirements.

Start with the purpose

State the purpose before creating the table: are you identifying attendees, comparing dates or assigning tasks? Each column should be necessary or genuinely useful for that purpose. Fields that might be needed “one day” can be left out initially.

A potluck list may need only a first name or initials, attendance and contribution. It does not require a full address or phone number. A training list can usually record the participant and their attendance decision without further explanations.

Treat the table link as a key

Tabble does not use user accounts. Every table receives a long, unguessable address. Anyone who knows the complete link can read and change its contents. This simple access model makes collaboration easy, but the link should be handled deliberately.

Send it only to the intended participants. Do not publish it on an open website or public social-media post. Use a more appropriate communication channel for individual confidential details.

Reduce data without losing clarity

Consider these options:

• use initials or first names instead of full names,
• omit contact details when the group already communicates in a chat,
• describe a dish as “nut-free” rather than linking health information to an individual,
• do not record children's birth dates, addresses or other detailed information,
• remove entries that are no longer needed,
• export only important, non-sensitive results when a copy is required.

Data minimisation does not have to make a list vague. A specific title, clear columns and a short accompanying message can replace many personal details.

Examples of compact structures

A group scheduler can work with a name and several date options. A potluck list needs a name, attendance and contribution. The training list does not require medical reasons for an absence. A parent-teacher appointment table should not contain discussion notes or information about children.

Rule of thumb: If a detail is not needed for the shared decision, do not collect it in advance.

Retention and your own copies

Tabble is not intended as a permanent archive. Inactive tables may be deleted no earlier than 30 days after their last access. Remove personal information that is no longer required and export only the results that genuinely need to be retained.

For recurring events, creating a fresh empty table is often preferable to carrying old participant information forward for years. A template provides the same structure without retaining previous entries.

A quick check before sharing

Read the title, columns and examples once more. Does the table contain only necessary information? Is it clear who should receive the link? Are there sensitive details better discussed directly? This small check takes little time and prevents unnecessary data collection.
