What Should You Never Share Online?
Some details must never appear online in any form: identity numbers, live location, and credentials top a short permanent list. Others depend on context and audience. Knowing the difference protects more than any tool. (EFF Surveillance Self-Defense)
Sharing feels safe because harms arrive months later through strangers. This guide names the never-share list, walks risky categories one by one, and ends with a checklist to run before every post. (Google Safety Center)
Plain and simple: Post nothing that enables impersonation, theft, or physical harm, and run every share through audience, permanence, and necessity checks first. Make the gates automatic and sharing stays joyful instead of risky.
Why Sharing Feels Safe
Sharing feels safe through three illusions working together. Audience illusion assumes only friends watch public posts. Permanence illusion assumes deletion works everywhere reliably. Distance illusion assumes strangers cannot reach across screens. Screenshots defeat deletion, archives defeat editing, and search defeats obscurity daily. Harms arrive months later through patient strangers. Scammers harvest patiently while victims forget freely. Understanding the illusions vaccinates better than any rule list. For the trail mechanics, see your digital footprint guide.
Safe feels instant while harm arrives later. Judge sharing by the later date.
Identity Documents and Numbers
Identity documents unlock impersonation directly. National IDs, passports, and licenses enable account takeovers and fraud. Full birth dates plus names anchor identity theft firmly. Document photos, even partially covered, aid forgers enormously. Tax and medical numbers open financial and health fraud. Never photograph, post, or message these except through official secure portals. Store copies encrypted and offline only. One posted document haunts for decades. (IdentityTheft.gov)
Shred old documents through crosscut shredders, never trash bins. Physical copies leak as surely as posts. Destroy what you no longer need.
Location in Real Time
Live location endangers bodies, not just data. Real-time check-ins guide burglars to empty homes. Running-route maps reveal home addresses through start points. Event posts timestamp your absence precisely. Geotagged photos embed coordinates invisibly. Children locations endanger the most vulnerable directly. Share trips after returning, never during. Delay posts by days for sensitive places. How location detection works shows the technical side.
Disable geotagging in camera apps permanently. Coordinates embed silently by default. Settings beat vigilance for invisible metadata.
Kids and Family Details
Children details deserve the strictest standard you hold. Full names plus schools enable pickup fraud and grooming. Photos in uniforms identify institutions instantly. Birth announcements with dates feed identity theft. Other parents posts need your consent conversation first. Schools publish enough already without home help. Model restraint so children inherit careful norms. Their digital trail starts with your choices entirely.
Review school and club postings featuring your children termly. Institutions overshare routinely. Request removals firmly and early.
Travel Plans and Routines
Routines and plans arm patient observers cheaply. Countdown posts announce exact absence windows. Daily gym and commute patterns map predictability. Work badges and office photos expose employers and roles. Conference check-ins reveal travel plus empty homes together. Package photos show addresses through labels. Pet names double as password hints commonly. Vary routines visibly and post retrospectively. Predictability is vulnerability wearing a schedule.
Ask travel companions to delay their posts too. Group trips leak through friends feeds fastest. Coordinate silence before departure.
Money and Work Details
Money and work details invite targeted fraud precisely. Salary screenshots enable social engineering richly. Card photos, even partial, aid thieves. Client names and internal tools expose employers to attacks. Unreleased projects breach contracts and trust. Layoff vents alert scammers to vulnerability. Keep finances and workplaces off public feeds entirely. Separate professional channels from personal ones strictly. Data brokers already hold plenty; add nothing.
Blur backgrounds in work-from-home video calls always. Screens and documents peek constantly. Virtual backgrounds guard reliably.
A Sharing Checklist
Run every share through three gates before posting. Audience: exactly who can see this, including strangers and future employers. Permanence: assume screenshots and archives keep it forever. Necessity: what does sharing gain versus keeping private. Strip metadata from photos before uploading anywhere. Delay location posts until home safe. Ask depicted people first, especially children. When any gate fails, keep it offline. Three gates take seconds and prevent years of regret.
Run the three gates on old posts quarterly, not just new ones. Retroactive pruning matters equally. Past shares deserve present judgment.
What About Old Posts From Years Ago?
Old posts deserve the same three gates applied retroactively. Scroll your oldest visible posts on each network once a year. Delete anything naming schools, addresses, employers, or routines. Untag yourself from friends photos that expose details. Request removals politely where others posted you. Archives may keep copies, but smaller footprints still help. Past selves posted freely, and present selves clean deliberately.
Set a yearly reminder tied to a memorable date. One session per network keeps the task small. Maintenance beats archaeology.
How to Teach Kids Safe Sharing
Children learn sharing norms by watching you first. Narrate your own gating decisions aloud while posting family moments. Grant teens growing control over their image as they mature. Role-play scam messages and overshare traps together safely. Praise cautious choices more than clever posts. Schools teach typing while homes must teach judgment.
Review their feeds together monthly without spying tones. Curiosity plus respect opens conversations punishment closes. Guide, do not surveil.

Common Questions
Is private messaging safe for sensitive details?
Safer than public posts but never truly safe. Recipients screenshot, accounts get hacked, and providers retain copies. Reserve messaging for low-stakes sharing. Official portals handle the rest. When in doubt, leave it out.
Should kids have no online presence?
Up to parents, but minimal is wisest. Avoid names, schools, and routines entirely. Let children choose their own presence later. Restraint now buys them options.
Do hashtags increase risk?
Yes, by sorting your posts for strangers efficiently. Location and event tags guide observers precisely. Tag retrospectively or not at all. Discovery cuts both ways.
Can I delete past overshares?
Request deletion everywhere posted and ask reposters kindly. Archives and screenshots may persist regardless. Monitor name searches quarterly. Past posts deserve the same gates retroactively.
Is it safe to post vacation photos after returning?
Mostly yes, once home and routines resume normally. Strip location metadata first anyway. Avoid revealing ongoing absence through comments. Delay detailed itineraries indefinitely. Retrospective joy beats real-time risk.
Should I use my real name online?
Depends on context. Professional work benefits from real names while hobbies and opinions suit pseudonyms. Never combine real names with locations, schools, or routines. Separate identities per role work best. Choose deliberately per platform.
Final Takeaway
Never share what enables impersonation, theft, or harm, and gate everything else through audience, permanence, and necessity. Post less, live more, and review often. Continue with your digital footprint guide and how online anonymity works.
